    But shouldn't the engine try to start. I always thought that anything over a hundred it should atleast hit on starting fluid or gas in the plug hole. The timing marks all line up. I checked valve clearances and everything looks good.

Check the firing order is not 180 degrees out
120 psi is very much on the low side and indicates a worn engine
should be up around 155-160psi

SOURCE: chrysler 3.3 vin r v6 mini van, starts then dies

Charlie. You have replaced the ECM on your van?.
Kedwin,, Your problem is, the computer on that 3.3 L.
Need to be programed with the VIN nember of your car.
The Antitheft System will disable the injectors due a incorrect VIN, Bucause the body computer is not recieve the correct pasword between 5 seconds after start up.
YOU have 2 options. 1 get a ALOHA Smith. some of they have the computer required to program ECMs.

The other option is: Get a new ECM from the dealer, They will program if ask for that.

NOTE:::::: Other way is . Put the body control module with the computer from the same car.

OK... I hope this work for yours.
If NOT letme know I can look for more information.
Thank you.

Most Chrysler cars do have an anti-theft system that can cut out the engine.

I would call the service department, with your VIN handy, and see if yours was equipped with one, and what you need to reset it.

If that isn't the problem, your EGR valve might be bad, or the sensor for it. I've seen a lot of cars where if either the valve itself, or the sensor are malfunctioning, the car won't run properly.

I would also check your MAF and IAC, as those can cause the car to not run.

If you can, get an OBDII code scanner, and pull the codes from your car, they might give you a more specific place to look. (Most parts stores will let you take one home, you put a deposit down, and get it back when you bringthe scanner back to them)

test and see if you have spark and fuel preasure, you may have bad feul pump, common problem is the fuel pump goes bad, but check before replacing.

sounds like youve really done your home work all that comes to mind now is try a cam posistion sensor this would keep your car from starting as well if that is good you can aslo try a crank sensor. you will get all of the readings that you are getting and these sensors can still be bad.

did you use aftermarket crank sensor? if so that might be your problem. dealer has several different ones, by providing vin number, but there is only one after market for all optimas 01-05. try to connect thick pink wire and thick orange wire together on the ignition failure sensor. you might have the same problem as me. good luck.

Check for spark.. pull one spark plug out set it on bare metal(away from cyl hole fuel could light from spark) turn vehicle over and look for spark should be a nice lightning bolt looking spark... blue spark is weak spark.. and see if it's getting spark...,, if not,,."try new plugs.,wires,distributor cap&rotor " also first.spray a little starting fluid down the injection system turn it over and see if it fires.if it does then it's a fuel issue prob not electrical... try that.hope it helps

I have a 2001 3.0 ford taurus compression on all cylinders less than 90 psi


The car should start, even with low compression in some cylinders. Since two things are needed for combustion, fuel and spark, you need to figure out which is the problem. Remove a spark plug (or buy a spark tester from harbor freight) and check for spark at the plug. Without a tester, simply attach the plug wire to the plug while removed from the engine and rest the base of the plug on the engine block (grounding it). Have someone turn the engine over with the key and observe if you see a hot spark jumping the gap of the plug.
Recommend you go to the library and borrow a copy of Chilton's for your car model.

97 geo will not start


You probably know, an engine needs compression, fuel, and spark at the right time to start. So one of those three components are missing.
Will it try to start if you use starting fluid sprayed into the intake? Have you checked compression on all cylinders ? Is the spark blue or white, or is it yellow ?

Engine turns over but wont start? it has spark! and fuel!


Pull out # 1 spark plug and put back into plug wire, rest on motor block so that end of electrode is against metal. turn motor over and have a finger or compression gauge in # 1 cylinder, check to see if spark occur at same time as compression (compression will blow air past finger or raise gauge). When you say it has fuel do you mean gas tank has fuel? Are you sure fuel is getting to the cylinders? are plugs wet with fuel? Does it turn over but kinda thumps or backfire (Caugh)? Check the spark and compression first. if they don't happen at same time, the timing skipped or belt broke. if all is good pull plugs and inspect, could be flooded (WET) from fuel. either replace or spray with starting fluid and compressed air to dry them. spray starting fluid into air intake if starts then stalls, try again, if same thing happens then you have a fuel problem. try these suggestions first 1/2 hr time table, hopefully sucess, if not it sure indicates fuel.

I bought a 1997 Chevy Blazer that was not running. I put a new battery in it and checked for spark. It had spark going to the main wire on the distributor, but the fuel pump was not pumping. I sprayed...


An engine needs 3 things to run fuel, spark, and air, but they must occur at the proper time, that being said, buy, or borrow a noid light. This is a light that you can plug into the injector to see if it is getting the pulse from the computer, do not use a test light, you will fry the computer for sure. If the injector pulse is there you have to check the timing to be sure the timing chain has not jumped. Bring the number one cylinder up on top dead center of the compression stroke, then pull the distributor cap off and make sure the rotor is pointing at the place on the cap where the number one wire is hooked on. If it is the timing is good, if not it is possible that the timing chain has jumped or someone has installed the spark plug wires incorrectly.

1997 Chevy Silverado 1500 4x4 will not start. Getting spark checked all fuses, changed rotar - spark plug wires,


Have you checked the fuel pressure? Fuel pumps are a common failure item on those trucks. Pick up a cheap fuel pressure gauge and hook it up to the shrader valve on the fuel rail. With the ignition on and you should have 55-65psi. Even if it's a few psi below spec it could stop the engine from firing.Once you determine the fuel pressure isn't adequate make sure you have a good power and ground at the fuel pump. If that checks out, time for a new fuel pump module. I recommend only replacing it with an AC delco unit, I've heard bad stories about aftermarket replacements.
You could also spray some carb cleaner or starting fluid in the throttle body and crank the engine over. If it runs for a few seconds after spraying starting fluid in you know you have a fuel delivery problem.

1997 chevy blazer getting fuel and spark but not starting, only backfiring through carb.


You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 63-64 lbs.
If you have all 3 then move on to injector pulse to all injectors.
I think each injector is on a separate driver on that one.
Check for pulse to all of them.

You may be weak on fuel pressure . even a couple of lbs low on a cold start will cause a no start.
Double check cold start cranking fuel pressure. If under 63-62 lbs you have problems.
one test is to give it a squirt of carb cleaner not starting fluid. If it starts then you have a fuel pressure problem.
Run the full fuel pressure test and post back pressures.
Here is the guide lines on testing.
Hard to start cold.
Check cold start fuel pressure.
Check engine running fuel pressure.
Check engine running on the road fuel pressure.
Then shut it off and watch for fast leak down.
Pinch off at rubber part or block off return line and check full pressure.
Later V6 and V8 gm engines should have 60-66 fuel pressure.
Cold start should be 64-65 lbs of pressure.
If you do not have full fuel pressure on a cold start the injectors will not squirt fuel. Do not leave home without it.
Engine running should be 60-66 lbs pressure depending on engine load.
Full pressure with return pinched off should be 75-85 or more.
And if it has a fast leak down after shut off you have a leak.


The 75-85 is only a check on the capable full pressure of fuel pump.
If you can not find the rubber return line check full pressure by plugging return line or just or the true full pressure can be taken direct at the end fuel filter.
What are the pressure readings that you have when done.
What are your cold start pressure readings?
Post back what you have. Good luck

I have a 1999 gmc Yukon it is getting fuel and spark i even sprayed starter fluid in the intake but it still wont start it turns over good but wont start


ok make sure you have good fuel pressure
you must have good spark must fire a spark tester
if all that is good then check compression
and don't use STARTER FLUID on a GAS ENGINE it can blow a hole through the piston
hope this helps

I have purchased a 1989 E350 and it has been sitting for about ten years. it was running when it was parked. It has the EFI 460 engine.I have a new fuel pump pulling and returning fuel to a five gallon jug...


80 - 90 psi isnt enough compression u need minimum 125psi per ciylender to make the fire. pull the plugs on it and pour a tablespoon of trans fluid down each hole this should recondition the rings. let it sit overnight and go out and turn it over it will push all the fluid out then replace the plugs and hope for the best. if still readfing 80 - 90 psi u will need to do heads on the vehicle.

What coul be keeping my 1986 honda civic from starting? The plugs all spark, the fuel pump gives gas to the carb, Ive changed all plugs cap and rotor and have tried spraying starter fluid directly into...


It cranks really good sputters a little and makes some loud pops but it will not turn over? FYI:Cranking and turning over are the same thing. When was the last time it ran. The gas could be bad. Did you get new plug wires as well. Try testing the distributor, remove a spark plug, plug it back into the wire, and touch the threads to ground and crank the engine. It should spark. Keep your fingers away, that's high voltage. Remove all spark plugs, spray some starting fluid in each cylinder, then crank the engine with the plugs out. This will clean any debris from the cylinders. Engines need backpressure to run properly, a major exhaust leak hence the popping, could cause it to not run. If you can get it started try to keep it going, full throttle, keep in the starting fluid, it could just need to get warm. I used to have one of them and they don't like it when they're cold.
