Place a spark plug tester in your number #1 ignition lead and confirm spark.- No spark = possible ignition module failure if spark from coil is present.

Test the fuel line pressure for 12 PSI.for throttle body fuel injection systems on 1987 to 1995 - If reading is low replace fuel pump. If reading is zero lbs check relay.

Compression test for acceptable compression.

If you have spark, fuel and compression, static time the engine and try again to start the vehicle.

PS: If your vehicle is a standard shift you have a clutch safety switch and a column mounted ignition switch that should also be considered.

SOURCE: 2001 gmc jimmy not starting

Did they do a fuel pressure pressure test to determine that its fuel pump? And if so what was the p.s.i.?It should be around 55 to 60 p.s.i. a few pounds under 55 p.s.i. Pump needs replaced, Your shop should have chk. this when it was there the first time. Did they by chance chg. the fuel filter, that can hinder it from starting too.

You mentioned that it appeared that you were not getting spark but what process did you use to see if you were getting spark or not?

Changed IAC valve 94 gmc jimmy v6 4.3L. whenever the engine gets to normal running temp it shuts down an won't start until engine is cool. Could this be a bad MAP sensor? Or fuel injector solenoid?


Could be a bad coil, or ignition module right by the coil. Both will cause this. If you loose fuel pressure, it would be the pump. But pumps will usually start chugging before the engine dies. Most times it is the coil.

this is indicative of a faulty ignition switch or ignition circuit.
When you have it in the start position the power is divided between the coil and the starter motor. hence it starts
when you let the key go to the run position the power is stopped to the starter but a new circuit is opened to the coil hence providing power to the coil for the engine to keep running. There is a resistance wire to the coil that lowers the voltage for running. Your problem will be in that run circuit if not in the ignition switch

It turns but it wont start,it has gas and power


Pull off the coil ignition cable at the distributor and check for spark coming out of coil when cranking engine over. Use a heavy rag or glove to hold the wire 1/4 inch from a metal ground. Should see a strong blue spark when cranking to verify ignition is good. If no spark, check for battery voltage to coil on the coil primary. If you have current to the coil, suspect a bad coil, ignition module, crank position sensor, or cam position sensor, or pcm. The coil, ignition module, and sensors can be tested before replacing.

The problem may be the engine coolant sensor. If the sensor fails the engine will stop when normal operating temperature is reached . When engine is cold it will start.

Check your spark plugs and see if they need to be replaced. Check the gap on the spark plug. You may have low compression, timing belt or chain should be checked as well. Check the computer system in your car. Is your check engine light on? Maybe your crank sensor is not working properly. Try these and if not get back to me and we'll try more possibilities.

Engine not start up i install new battery,new ignition module, check fuell presure 45 psi. coil, order firing


Check you Cranckshaft Position Sensor....i have a 99 GMC Sonoma and i had the same problem. It would not start in the morning, and i replaced everything i could think of. ignition coil, distributor cap and rotor, wires and plugs and no luck. I could hear the fuel pump prime when i turned the key on, so i knew it was getting fuel. As it turned out the sensor (which is located on the front and bottom of the engine block just behind the Crankshaft drive belt pulley.) and was preventing the engine from starting. Check that out and that may be the cause of your problem
