Ignition Question

[dartvader]

Sorry if this is a stupid question Ive been searching so much my head is spinning, this thing they call stator in the distributor does it have another name, maybe distributor ignition pickup is that it?, my car has developed a backfire and hesitation at high rpm more than 5000, it seems it loses spark, Im sure its not fuel cause everything is new, is their a way to test the ignition module
bad grounds can do this too right, ohhh I forgot sometimes the car is hard to start it turns over but won't start right away amnit:

pip = profile ignition pickup, hall effect sensor, stator are all the same thing.

Don't think there is a way to bench test just the module, but I do remember people talking about a way to troubleshoot a spark problem and isolate it to the stator. You should do a search.

is the TFI good? i hear that can cause the same issue.

you should try and locate someone with a 94/95 to swap parts!

any codes?

The irony is that the PIP can cause you to lose fuel.

The idea Scott was getting at (it won't apply here unless the issue gets worse): if the car won't start, and you have neither spark nor injector pulsing (tested with a noid light), the PIP is likely.
If you have no spark but do have injector pulsing, the PIP should be ok. At that point, the ignition coil, TFI module, etc (in the ignition) are likely at fault.

Right now, that doesn't help you much. Do pull codes - that's a great opportunity for a soft code to be stored. I'd also note that 5K+ RPM is when a weak ignition can rear its head. Too large of a spark plug gap or spark plugs that don't conduct very well (read Platinum) can start to have a high-speed miss.

Random thoughts.

Good luck.

Im thinking about the TFI module too ths MSD distributor I have has only about 2000 miles, the coil about 800 miles, but the TFI module .when I got this car it had 200.000 + miles, since then it has a new engine new tranny, differential and some other engine stuff, I have gotten no codes, Im running autolite 3924 gapped to 0.45, today Im going to check the ground wires to rule that out...... thanks guys

Try running the plugs at 0.045" and see if it helps.

Tossing parts at things can get pricey.

Best of luck with it.

Today I changed the ignition module checked the grounds, could this problem be caused by bad gas, now that I think about it all this started when I put new gas in the car I have 10.5 to 1 compression
and yes the plugs are gapped at 0.045

I didn't mean to sound sarcastic before. People often mistype the plug-gap spec and more than once a new member actually has attempted to gap his plugs at the listed spec (nearly half an inch) after doing a search. That's why I clarify.

I'd still want to know that you are not running out of fuel pressure/volume at higher RPM. The reason I consider this is that a weak pump can also cause prolonged cranking before the motor catches.

Good luck.

I do have a new 255 lph fuel pump and regulator fuel psi at 40 new 30 injectors I put in a new ign module
I don't know much about this cars this is my first one but its either the gas or my low miles MSD distributor is going south, everything else is new on the engine, I'll see if I can find one of those things around here to swap and see
I'll update when I find the problem, seems many people are having the same problem
thanks for taking your time

just wanted to update everybody on my situation, well today after trying almost everything we changed the ignition pickup, stator or PIP the car is running fine again, that was the problem, so don't think just because you have a relatively new distributor this stator cant go bad mine had less than 5000 miles
