I have a 78 coupe, with the 425 EFI, it starts everytime easily, engine is good, but if engine gets hot and i turn it on, i have to wait a long time, before i can start it again.

Any advise on this?

Thanks

What is the BENDIX 161 xxxx number on your ECU? Check your MAP voltage.
Note the 5 pin test connector opposite the connector. It has 3 contacts, a gap cut in the board, and 2 more contacts. The very last contact above is the MAP voltage. With ign on, engine not running, it should read 7 or 7.5V ref to ground. Check your timing chain by lining up your timing mark. With distributor cap off, rock the crankshaft by hand, see how far you must go before the dist rotor starts to turn. 6 degrees means the timing set is completely worn out. Bruce

On a 78 you don't have to open it, just find the test connector opposite end from main connector. That is if you have the ECU I think, what is the BENDIX 161 xxxx number on your ECU? You could also apply vacuum to the ECU, and see that the voltage drops to a couple volts at high vac. Bruce

next week i plan to start messing with the engine, will change the spark plugs, cables, oil, oil filter, air filter, TVS valve, clean injectors, change radiator fluids, check transmition oil, differential and last but not least, fix the vacuum lines.

after all this if still there is some problems i will mess with the ECU and etc...

i will keep everybody posted, i am dying to drive this car.

I will also change the brake booster, i received a re-manufactured one from A1 Cardone.

i got also the new trunk seal, and my trunk is full of parts, im just waiting for the air filter and oil filter which i purchased off ebay, the only way to receive it in Brasil.

I rather send you my ecu and you do the job, I will email you today!

I think napa is charging way too much for those, let's not forget that they also charge a extra $84 for core.

And I can't purchase online, I would have to wait until november and go personaly to a store.

Ok, problem FIXED...

Turns out that, no problem in the vacuum lines, no problem in the timing chain or sprokes...

Bruce Roe was dang right!

Problem was only the ECU, i sent him the module, 10 days later i receive it back, just plug it and voila!!! Everything worked as is supposed to work.

Bruce Thanks very much!!! was the best spent money ever!

This guy is good!!!

cheers bruce!
