Team TB,
I recently purchased a 1986 GN that has not run in many moons. The previous owner replaced tank/pump assembly. It currently has a TON of ATR pats like the air filter(black cylinder) looking thing, a 7th injector, an ATR wastegate and goodness knows what else. I plan on getting it running properly but need some initial guidance with an issue.
The vehicle has a very , very long crank before it starts. I'm talking 30 seconds or so. When cranking, it will also seem to pop through the intake. After about 20-30 seconds of cranking, it will start and seems to idle well. I have not let it run for more than a minute or so at a time. Once it has started, it will restart normally. It cranks like it should and fires up with no extended crank. I have an old snap on brick scanner and pull no codes.
Can anyone provide some guided diagnostics to start? I have not checked fuel pressure or leakdown due to the pump and tank being new. Assuming that pump is ok. I will be sure to check over the weekend. What is confusing is the popping while cranking until it starts.
