Hello I am new to the forum and would like to say hello to all my new friends. But now down to my problem I have a 88 5 speed pickup with the 3.0 v6 naturally the head gaskets went out and I replaced them got it together and something is keeping it from getting fuil it has spark and fuil in the fuil rails and will start for a moment and stop thought it was cam sensor Can not find it any help?

 

Fuil?

"starts for a moment and stops" is the classic sign of a problem in the VAF-COR circuit. Jumper FP to B+ in the diagnostic connector to force the fuel pump to run with key-on. If that clears up your problem, your VAF and COR are not keeping the fuel pump running once the engine starts sucking air (and after you let go of the key).

PS You DO have all the induction plumbing (large black tubes) connected, don't you?

 

Yes I put every thing back together excuse my lack of knowledge but I took the throttle body off of the intake and checked to make shire my injectors where clicking and they are but I'm not shure where you talking about to put in a jumper wire?

Yes I figured it out and it did not help its like there is a sensor or something shutting the truck down as soon as it starts

 

Well, just so you know, there is no cam sensor (cam position is derived from the G signal).

 

I'm not shure what the G signal is but all I know so far is that it is not a fuel pump issue or spark but the injectors I noticed are all firing at the same time should that be?

 

Yes, they all fire simultaneously. '80s technology.

 

Well I got the truck to run .... Very badly tho I'm going to put a timing light on it but not shire if that will fix the very rough idle or not

 

Any vacuum leaks and all hoses routed correctly? These trucks do not like leaks at all.

 

There are a few hoses on top that are cracked but not bad don't know if that could be it but wouldent think so

 

I don't know the 3.0 but I have had battles with a 22 motor due to leaks.

 

I'm not really familiar with these toyotas at all but it has me pulling out my hair

 

When was the last complete tune up on it with all new ignition parts, filters and such? I have seen people try and trouble shoot a motor with worn parts on them and that can cause all kinds of issues. Start at the basics of complete tune up, check for leaks, make sure all connection are made correctly, check timing, valve settings and such. Once that is done see what symptoms remain. Use quality parts. Check that all ports are free of carbon from the EGR.

When I get into a situation like this on a truck, what problems are left usually pops up at to what is causing the problem after all of the basics are done. Fixed more then one truck this way and is needed to get a truck back up to condition.
