Rico,pull the valve covers and check the lift. I'd almost bet the cam is worn. A new cam and lifters is fairly cheap from Nova and it can be changed in a day .

I'll have to check that. But since this is only a 305 I'm a bit hesitant in dumping too much money into it. I took the egr valve off and lo and behold it was stuck open. I gave it a shot with compressed air and it closed. Then I checked for leaks by pulling a vacuum on it and it worked fine. Just stuck open again.... I have it soaking in brake cleaner and will have to pick up something to remove carbon deposits. So that may play a part in the issues. So if I can locate a different distributor and check if the cam is worn (hope not) then with luck all works after that.

you need to make up a block off plte for the egr. if its sticking open that the place to start.

Let me know if you want one. LOL. Way ahead of ya! Just not as fancy as yours. I just cut it out with a mini grinder! Same shape as the EGR. ;D Uploaded with ImageShack.usAlso picked up a cheap used distributor which appears to be in much better shape than my existing one. Uploaded with ImageShack.usHope this works!

Don't change both at the same time. That way you know what the cause was.

Well this piece of crap is starting to piss me off Put the EGR back on. WOuld not run. Bought a rebuilt distributor from bargain auto. Won't run. I should clarify that. Would crank and start fine but would shut off after a couple seconds. Took off coil and metered it. Tested fine. Put it back on and connected it to a spark plug just to make sure. Very strong spark. Next check fuel pressure gauge while cranking. Showed a steady 13lbs. Next pulled the breather and noticed the injectors would spray on start up then stop after only a couple of pulses. Could this be the new module on the distributor? Didn't thinkECM bad? Know of anything else to check? Didn't think I had the timing off that bad!!

Immediately shutting off sounds like you have power from the ignition start position but not run position. That would be something new though, not your recurring problem. You could test your run wire for power when the key is on.
After confirming run power you could also jumper the fuel relay and see if you have constant fuel with the key in the run position.

You could test your run wire for power when the key is on. After confirming run power you could also jumper the fuel relay and see if you have constant fuel with the key in the run position. Good suggestions. However the buggy is not wired that way. No key for "run or start". All on toggle switches. One switch for the pump, another for ignition. Both of which have been checked and work fine. I have a pressure gauge in line just before the throttle body. When I turn on the pump it pressurizes the line and when its cranked it shows pressure at all times. Then when the engine shuts off the pump continues to run (showing pressure on gauge) for a few moments then shuts off. So that would indicate the relay and fuel pump are doing their thing. Just have to figure out why the injectors aren't pulsing. I did a continuity test on the wires coming from the ignition module to computer and all appears fine. No broken wires. So I hope the computer didn't crap out. Anyone have a spare working distributor laying around? Starting to wonder if the module I just got is junk....

Rico ,I got a module here laying on the bench for you.I'll be around most of the day tomorrow if you want to pick it up. Right on. However I need the whole distributor. I needed the core when I bought the new distributor so no longer have a spare that works. When I called the place I bought it from if I were to swap out the module to test if its bad or not I would void the warranty. Right now they said they could just replace the whole thing free of charge. Running out of ideas. Probably something simple

I think I have a 7747 ecm in the garage if you want to borrow it. It would be mid week before I could get it to you.

dosen't make sence it wouldn't run without the egr. seems like the more u search for the problem, the more problems you are causing. why did you get rid of your old distributor.

A bad EGR, from what I've read, could be a reason the engine was running like crap. So thats were I looked first. But you're right. That would not cause it not to start. As for the distributor. The whole thing started when I decided to check for bad connections. Was checking wires around the coil etc. Then I wondered if there was corrosion under the cap or rotor was bad. Buggy sits most of the time. When I took the cap off the pick up was solid green and the coppers had turned powdery. And the plugs going into the module were all powdery green as well. Figured something wasn't making contact. So instead of screwing with replacing individual components I just replaced the whole thing. Now the engine won't stay running. Which tells me a possible bad module (or ECM) in my new distributor since thats the only new component.

Back in biz! Took parts from 3 different distributors plus a module that Andy had that came from a 6 cylinder distributor and put them together and installed. Vrooom. Fired up first try and ran fine. So it turns out my new distributor was indeed a piece of crap! Now to exchange the crap for one the works! Back to test wheeling!
