You need to check and make sure you have fuel pressure, then check for spark at ignition, if those check out then check for pulse width at the injectors. That basically is the electrical signal which tells injectors to spray fuel. Use what is called a Noid light on injector pulse width check. that will eliminate all possibilities other than internal issues with engine. I.E. broken cam, broken timing components, obviously if all I mentioned checks out then run compression test. Good Luck

SOURCE: astro van wont start

Did you check for spark? Is it getting gas at the fuel rail? If there is no spark then it could possibly be the crank position sensor, ignition module or coils but the coils do not all go bad at the same time.

SOURCE: bad stumble on acceleration pops through t- body.

Sounds like the fuel pressure regulator. Could also be that the timing jumped. But I'm leaning towards the pressure regulator. Hope that I could help. Best wishes.

How to change cam shaft sensor on 1998 saturn sl1


There is not a cam sensor on the 1.9 sohc or dohc engine. The ignition module looks at the collapsing magnetic field of the ignition coil to determine cam reference.

Did you mean crank sensor?

Are you coming up with a code for the cam sensor?

If so the fix is usually to remove the coils and ignition module from the transmission. Clean the area they mount to with a scotchbrite pad until all the corrosion is removed. Reinstall the ignition module and coils using new bolts available from saturn/GM. Clear the code.

In some cases the ignition module or the coil or the ignition wires can also cause this code if they are bad.

Fuel pressure is right on and has good spark at plugs. No voltage at injectors. Need to determine if it is ECM or ignition module. 1992 chevy cavilier


Check the input voltages to the ignition module. If they aren't what they're supposed to be, it's ECM or wiring fault. You need a wiring schematic to troubleshoot accurately on a problem like this.

Ok here we go again still have a no spark condition $ 2,300 dollars invested so far on this no spark condition Here is what has been done New computer programmed at the dealership - new ignition...


If you connect a scan tool and go into the data stream and crank the engine over does the scan show any rpms? Also have seen many times where the pcm connectors are corroded or wires are frayed. The pcm is definitely not in an ideal location for these vehicles. Let me know if the rpm's are registering on the scan tool or not.

Had no spark. Replaced ignition mod, 2 coil packs, and computer. I now have fire; problem is engine will not run, the fuel injector sprays fuel (too much i think). When i unplug the injector the engine...


Check for any wiring pinch which might have occurred when the injector was replaced. The injector is driven directly by the computer, so it seems to point at the new computer as being faulty. (pulse signal is always 'on')

New plugs an wires,coilpak what else could


This is the only possible ideas I can thing of :

Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues

I know you did these two things:
Faulty spark plugs
Faulty coil or related wiring
