SOURCE: my s10 will turn over, but wont squirt gas through injecter

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

SOURCE: 1998 Chevy tahoe Hard to start when cold

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

Try to do the crank relearn:
Ensure that your battery is fully charged before attempting the relearn procedure. Do not leave any battery charger or jumper cables attached to the battery. Close the hood completely. Some applications require that the doors remain closed during the procedure.
96-99 S10
1. Rotate the key to the start position to attempt to start the vehicle (the vehicle will not start).
Allow the key to return to the all position (same as if the vehicle would have started). The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
2. When the theft system telltale stops flashing (or turns oft) turn the key to the off position for 5 seconds and then attempt tostart the vehicle. The vehicle should start on this cycle.
3. Once the vehicle is running, the password relearn is complete.

2. The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
3. When the theft system telltale stops flashing (or turns off) turn the key to the off position for 5 seconds and then attempt to start the vehicle.
4. Repeat steps 1 through 3 two more times for a total of 3 cycles/30 minutes.
5. On the next cycle of turning the ignition key from off to crank the vehicle should start
6. Once the vehicle is running, the password is learned and this completes the cycle.
7. Clear any DTC's with a scan tool if necessary. DTC history will be cleared after 100 ignition cycles.

99 jeep grand cherokee 4.0 starts but wont stay running. no check engine light on


Many issues will not set a code so start with basic troubleshooting. Is fuel pressure correct? Is EGR dirty or sticking open? Is IAC dirty or sticking? Is compression correct? Bad coolant temp sensor, bad O2 sensor, clogged exhaust or converter all can cause this, even a bad vacuum leak!

My '99 chevy truck with 5,7L 350 will start but wont stay running. put new fuel pump and relay switch in


First you must determine if the fuel is stopping or the spark is stopping..If the fuel is stopping this could be a computer problem.. If the spark is stopping then it could be the IGN Module in the distributer. or any nomber of sensors. Squirt a little fuel directly into the Throttle body on the intake manifold.. If the truck runs longer its probably loss of fuel.. Do this several times to make sure, be careful and only use a small amounty of fuel.. you do not want a fire.. RE: Spark: Take a plug wire and an old plug..put the wire on the plug.. hold the plug against a good ground .. have someone crank the engine .. does the plug stop firing? The engine dies.. and will not restart for a minuet or so.. during this "no start" time do the plug test. If the plug will not fire during this time take the module out and take it to Orillys Auto parts.. They can test it.. really expensive part. Don't replace until you know it is BAD..

Car stalls, starts up then stalls again, starts up and stalls again


This could have several problems. #1 Fuel pressure due freezing water in fuel lines add thermal aid or rubbing alcohol . If you have access to a pressure gauge there is a service fitting on fuel rail that you can test pressure while driving and see if the pressure is gone when car dies this could lead to fuel pump electrical or more restricted lines. #2 intermittent sensor failure Mopar uses 2 sensors to control spark and fuel lose one could lose spark lose the other lose injection with a scanner they call it C/C sync ok (cam/crank) if no then check for each parameters for display.# 3 relay controls ASD and FUEL pump for voltage drops.

1996 jeep wont stay started and oil pressure gauge goes up and down


hot or cold engine , or both.?
the oil pressure will be in direct ratio to engine rpm. slow low, fast high
due to the oil pump connection to engine crankshaft.

stalls.: can be caused by 50 things, or just 4 in physics.
the EGR valve (if you have one, no engine stated)
can stick open and stall any engine, and in fact LOVES to. clean it.
1: list 12vdc to EFI. (spark and fuel brain) dash lights dim?
2: lost compression hot, ? compression tests.
3: lost spark, do spark tests. and timing, checks.
4: bad fueling, too much if floods, and misfires and stalls.
too little fuel, it starves and dies.

the 1 free test, is can you save the stall with a fast right foot.

we do the tests. avoiding those 50 guesses....
each tests are simple and the tools dirt cheap .

Stalling problems


By installing a fuel pressure gauge on service port on injection rail then drive car if dies pressure should be zero normal range 36-45 psi to keep the engine running low pressure could be stuck open pressure regulator. if pressure stays then you have eliminated fuel and move on to electrical problems such as spark.

89 ranger i was driving than it just stalled. i have spark, i have fuel but no fire. but it wont start, if i put starting fluid in the intake it will run for a second then stall.


If you can keep spraying staring fluid and it stays running then the fuel pump is no pumping. only with a pressure gauge can you test it

My probe is stalling at traffic lights. the rpms wont stay high enough to keep the engine running.


Most modern cars with fuel injection, have to maintain a certain range of fuel pressure. There is a schrader valve in the fuel line. At this point fuel pressure can be checked. Pressure is always present. This can be dangerous, even at low pressure. Hope this helps lbreen

Sputtering wont start no power


most likely a fuel filter problem. try takeing a rubber mallet {not steel} and pound on the bottom of the gas tank. this will sometimes dislodge whatever is clogging the filter screen. Your engine fuel injected and needs a certain amount of pressure to operate correctly. You can have a repair shop do a pressure test on the system.
