New Member Needs Advice/Guidance please

[86ATR]

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.

Where are you located?

When you turn the key to the on position, the fuel pump should run for a few seconds. Sometimes it is difficult to hear over the door chime. There are two relays on the passenger side inner fender. One for the A/C & one for the fuel pump. Check the pump relay.

I can't help with the "popping" you describe.

These cars require a substantial investment in either dollars, homework, or both, to maintain them.
