TPI swap no start--lost....
Hi guys,
I am new to this but I hoping for some insight.
I just finished swapping a TPI 350 into my 305TBI 1990 firebird. Of course, it will not start. So where I am at:
I have spark, the timing is set correct, I rechecked while cranking. I spun the distributor 180 just to be sure. I have good spark at the plugs. I rechecked the wires to make sure they are not crossed or mixed.
I have fuel pressure, kind of. When I first turn to run I get good pressure at the schrader valve. Then it dies right off. When I crank the pressue again opens right up, but dies off when I turn back to run. While cranking I pulled the fuel lines and it puts out good flow. I have a new fuel pump, TPIS regulator. The injectors have been pulled, cleaned and mapped. I was going to put power to the 'G' terminal on my ADL block but there is no connector there.
Anyone with advice would be great. I tried to search the board but for some reason I keep coming up with an explorer error.....I have been trouble shooting this forever and I am going nuts.
Thanks
Shawn

Personally, I'de jumper the pins at the fuel pump relay to keep it on steadily, then I would take an amp clamp and start tracing the 2 wires in search of zero amperage...

WHat memcal are you using? I had a stock AUJP from the dealer and it wouldn't start... turned out to be looking for a non-existant VATS signal. moates.net's chip adapter and a burn with VATS set to zero fired it right up.

I had a new chip burned from TPIS, I still have the old one and tried that as well with no luck. I have not had time to track down any zero amp leads yet, I did trip the fuel pump relay and it runs fine and holds pressure well.
I also noticed that my check engine light does not come on when I crank it over, I need to see if it is a bad bulb or if this is something else going on.
If it was looking for a non-existant VATS would I still get spark or would it cut that off?
I am off this weekend so hopefully I will get to mess some more with it and see how it goes.
Thanks again
