I know, probably the silliest question on the net, but I am trying to help someone on another forum, and I don't have a TBI L05 and have had almost no time ever looking at one.

Where is the FPR and how do you check the FPR operation? Can I hook at vacuum pump to it to check it?

Can anyone help? Pictures would be fantastic.

Problem is warm restart, it won't. Cold is fine, let it sit, it is fine. Mainly over 80F, cooler temps now, he isn't seeing the issue anymore. I am starting to think he is leaking down his fuel pressure and it is vapor locking or something. But with TBI pressure, should it be able to vapor lock?


Thanks a ton! I just don't wanna see someone get into wasting $$ for no reason.

 

It's on the underneath and the backside TBI unit. Just above the fuel lines.

IMO check the ignition module.
