GMC 2001 Sonoma 2.2L
Changed igmition module, plugs and wires, crank position sensor, Engine control module. I sprayed either into the inlet and no fire. I pulled a plug and shorted it out and I do Have spark. When I go to on with the ignition switch I can hear the fuel pump running. I then took tke fuel line off of the forward side of the fuel filter and I have a powerful stream of fuel coming out. What is next. The engine turns over but no fire. The engine originally shut down while i was driving and has not wanted to run since.
Spark plug calibration correct? New secondary wires up to specifications? Distributor located Hall Effect Switch working? No computer codes? All fuse boxes Ko OK ? No accesory alarm system jamming ignition? Spray ether -starting fluid- at induction air filter. Start engine. If it run, is a fuel - injector problem. No start, is a mechanical-timing problem.

Could be a problem with the cam or crank sensor, the ignition module, the plug wires could be on the wrong coil towers, or a fuel injector issue. Is the check engine light on when the engine is running ?
you may want to check to see if this engine has a crankshaft position sensor, that tells the computer when to fire the distributor to the right wire. It might be the ecm itself. The best way to see if it is getting fire is to use a test light and while someone cranks the engine check the number one plug wire for fire. If there is no fire to the wire it can be a faulty ignition module in the distributor , ecm, crankshaft position sensor, bad wire bad cap bad coil. Go through process of ilimination
The ignition module in the distributor is what you need to give the engine spark to the plugs. It senses signals from the PCM to regulate the spark control and this item is the part that took over the old style point & condensor type ignitions. It is time for a new one in your truck
Sounds like you may have a crank sensor or a ignition module,or pickup coil gone bad,you should use a scan tool to look for cranking RPM's,or pull your distributor cap and look for a green corrosion on the pickup coil wires at the module.
Pull plug wire and install a philips screwdriver into the plug wire get it 1/4 inch away from a good ground and crank the engine over, is there spark? if so check that you have fuel pressure buy renting a fuel pressure test kit from schucks or auto zone and turn the Key to run positionwith thegage hooked up, it should read 50 PSI turn key off and wait 20 seconds should still have 20 PSI of fuel pressure, if no fuel pressure check fuel pump relay, then check fuse to pump. if you have a bad relay and are not getting fuel then check the oil pressure switch to see if you have oil pressure at the switch if no pressure then the oil pressure safety switch has died and needs to be replaced and should stark after replacing. If you have fuel then check the timing to see if you slipped timing belt.
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
