Replace the sensor as it is not controlling the correct fuel ratio. Recheck for more moisture in the cap as the water is in the distributor and will evaporate up and affect the spark process.

Sounds like the cpi injector assembly. The fuel pressure regulator may be leaking. Or the poppet valves on the injectors may be sticking or shot. I replaced almost every part on my truck and that is what it ended up being the whole time. It's a common problem on these models. Hope this helped

Smell of the oil,to see if the fuel injector(spider)is leaking into the crank case,if so,the intake will have to be removed to repair the problem,oh,and change the oil.

Won't start


Check for power on the small wire at the starter with the key in the crank position. If there is no power than you will need to trace the circuit. A Year, make, model, and engine size would help a lot!!

My 96 acura integra won't start but turn over


Get some engine starter spray. Follow instructions on spraying into intake. This will serve as a fuel source to test spark/ignition. You will want help cranking the car while you spray. If car stumbles and tries to run, you have a fuel problem. If after trying for a few minutes there is no change, then I would bet you don't have spark. Of course you could go further and say there could be a timing issue, no compression, etc. But I would start with the easy stuff first.
When was the last time you did a tune-up? Are the plugs in good shape?

Sounds like your Timing Chain or Belt Are Damaged and Caused your Ignition Timing to Jump out of Time, Also check your Distributor Cap and rotor NOTE: if you have a Distributor ,Some are Distributorless. Pull your Spark Plugs out BEFORE you Do Locate #1 Plug its in Front of your Engine.And Trace the Wire to the Distributor Cap. If you have a 4 Cylinder #1 is in the First Plug in front of vehicle, if its a V-6 #1 Plug is on Left side first plug in Front. Depending on which engine you have will determine if your wires go into the Distributor cap Clockwise or Counter Clockwise. So BEST to Simply Mark them to get them back in same order.You'll need to Get the Enging to crank over and have a Buddy Put a Compression Gauge in #1 Cylinder and Bring it up to TDC (Top Dead Center) thats when the piston is up and gets the Gauge to Move up then your on the Compression Stroke, Then check distributor rotor to see if its pointed to where your #1 Spark Plug wire came off or at least close to it.Just hit the Ignition Switch off and on Until you have it showing compression on Gauge. JUST ON and OFF that Fast. If the Rotor is pointing To a different Spark Plug Wire in the Cap, Sounds like timing Jumped. Hope this will help you solve your problem or at least find it. If you don't have or not sure on How to do this i recommend you have a Qualified Mechanic Shop run the Tests. Thanks and Good Luck

Truck wont crank. we have put new distributor cap, rotor button, coil pack, plugs, wires, and fuel pump. we also checked our firing order.


you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.

Changed distributor cap now car will not crank


You should check to make sure that the rotor button is in place. Also check the coil wire and the fire orderr to make sure that no wires are crossed. These are pretty much the only reasons why your car won't crank with the distributor cap change.

ENGINE TURNS OVER BUT IT WONT START


There is no simple answer, there are to many variables. If you have access to a scan tool, pulling the codes should help. Without them its back to old school hunt and peck method. At this point we need to narrow down the problem. You need to test for spark.
  1. Tag and disconnect the spark plug wires from the spark plugs.
  2. Remove the spark plugs and install the spark plug wires to each spark plug.
  3. Ground (do not hold spark plug) the spark plug; check if spark occurs while engine is being cranked.
Crank the engine for no more than 2 seconds at a time to prevent flooding the engine with gasoline.
If you have spark, You will want to make sure you have fuel injector pulse, along with fuel pressure. If you have spark ..simply spray some starting fluid in through the air filter and hold the gas pedal to the floor and crank it over while spraying. If it fires up, you know it is fuel related( fuel pump, regulator, or ECM if no injector pulse) . If you have no spark then look at ignition coil connection and trace through to the distributor( if equipped ). The crank shaft sensor has a tendency to fail on these as well. This should give you a few things to test and check to start you on your way to narrowing it down. If you have no spark then look at ignition coil connection for power and trace through to the distributor( if equipped ). If it is DIS( no distributor). It may be the Crank sensor or the ECU. The crank shaft sensor has a tendency to fail on these as well.
The ECU uses the signal sent from the Crank sensor to trigger the spark and fuel injectors. ( make certain you have checked all fuses)

Timing belt broke ,just replace it but it won`t crank.it sounds like electric priblem


Only the 2.3 liter diesel is an interference engine. The 2.3 Liter gas is not an interference engine. I would guess the belt was not installed correctly. The belt broke so the cam was then out of alignment with the crankshaft. Unless you aligned it correctly it will not start. BTW, the belt must be replaced every 60,000 miles. I asume you have the timing cover off, put it back on and set the crankshaft at the 0 mark on the timing cover, remove the cover and don't touch the crank. near the bottom of the cam gear is a protruding piece of plastic with three raised areas, set the cam timing mark at the first pointer, closest to the passenger side . on the back part of the timing cover is a v shaped pointer set the distributor gear mark at the pointer, remove the distributor cap and verify that the rotor is pointing at #1. Loosen both bolts on the tensioner and using a pry bar carefully pry the tensioner away from the distributor gear, tighten the small bolt on the tensioner. install the new belt starting at the crank, then the distributor gear, then the cam, then over the tensioner pulley. loosen the small bolt and the tensioner will adjust automatically. tighten the tensioner bolts and turn the engine over by hand 2 or 3 times and make sure all marks line up ( the cam mark should now be at the center pointer with the crank at 0). I find it handy to paint a reference mark for the crank inside the timing cover.

'95 nissan quest stalled at a stop. Will not start, only cranks


I worked on a '93 Quest last year. Couldn't find out why it wouldn't start. It was the distributor shaft not held onto its rotating gear. The roll pin had come out of the gear on the end of the distributor shaft. When the distributor cap was off, the rotor was turning with the shaft while the engine was cranking. So I thought that was okay. But when I put my finger on the rotor and it stopped turning, that is when I found out the problem. It's a stretch, but maybe the techs missed it. Take the cap off, and if you can spin the rotor either way just by hand, the distributor gear has come loose.

Looks like they really covered a lot. I suppose next they will you to replace the ecu. Good luck.

97 saturn sl1 drove in fine, won't start just crank. no spark


Crank engine with distributor cap removed, is it turning?
(That is if it has a distributor cap, some newer cars don’t have one)is it turning?
Broken timing belt or chain?

Are you getting power to the + positive side of the coil (small wires) with key on ? Hint; I use a needle pushed into the back of the plug so as not to damage the wiring.
If you have power then wiring from the ignition switch is OK. It usually is.
Hook your test light to the - negative side of the coil (one end on the - terminal and the other end on a ground). You should have power on the - side of the coil with the key on and engine off.
Crank the engine while watching the test light. Get a flashing signal at the test light when cranking?
If so and you have no spark the coil is likely dead.(don’t rely merely on resistance tests for a coil, a weak coil can test ok for resistance but still give no spark.It happens but is unusual. I learned this the hard way!)
No flashing signal?
Check continuity in all primary circuit wiring for opens.
If they are good,
It is time to check the pulse generator in the distributor. (That is if it has a distributor cap, some newer cars don’t have one, if it doesn’t then the ECM or computer sends signal via the crankshaft position sensor and the camshaft position sensor)
With the engine in non-running condition connect your A/C voltmeter to the pair of wires at the pulse generator and crank the engine. You are looking for an A/C signal that makes 4-6 volts of A/C. Got this? If so the ignition module is dead or has a bad ground. If not (more likely) you have a dead pulse generator in the distributor.
If you have three wires in the distributor signal wire you have a Hall effect sensor. I forget how to test that one. (Chrysler stuff)


If this part of the primary ignition tests ok then check wiring to ECM pinouts for opens.Wiring tests ok.ECM as last resort.
Hope this helps...........
