Cranks but No Start (days before MR/C4 Gathering) - ZR-1 Net Registry Forums

RussMcB · 05-07-2015

I apologize for starting a new No Start thread, but I need to resolve this quickly, so I figured I'd post here today.

I got my car back from the body shop on Saturday (new paint came out great!), and I've been working on it a LOT since then. The car has started a few times since Saturday, but not in the last 2 days, and I'm getting close to panic mode.

What I'm hoping to gather from you all is a methodical process to identify the problem. I have a FSM but haven't found it useful because the steps require a scan tool, or technical knowledge I don't have.

Below are a few clues. Thank you all for any suggestions you may have. The car still needs a LOT of reassembly (front & rear fascias, interior, etc.), so this No Start troubleshooting needs to be quick or I won't be able to drive my Z to the Mountain Runs or the C4 Gathering.

The car cranks well but doesn't start.
It has a full gas tank and good fuel pressure (~50lb, Autometer gauge on a-pillar).
I installed the VATS bypass plug, and did the Starter Relay mod in February.
It has started twice since Saturday, but has not started in last 4-5 attempts (12 hours between tries).
I got it back from the body shop on Saturday. It had a no-start condition while it was with them. After I unloaded it from my trailer on Saturday it started right up with no issues. The car has had this behaviour since I got it in January.
Tonight Mark Litherman ("8cam") is coming over. With his help I'll see if the spark plugs are getting a spark. We can also swap parts (like computer). My car is a '91. His is a '90.
I'll check for codes tonight (but the last time this happened, the car threw no codes).

PS. To make matters worse, last night I closed the hood (for the first time since the paint job) and the passenger hood latch is stuck closed. I'm googling to get suggestions for that problem, too.
