Sudden strange starting issue, The plot thickens Options

[emerygt350]

The past two days, cold start took longer than normal. Cranked maybe 8 times before starting. This morning it took twice that, and now all of a sudden at the grocery store after starting just fine at my office (3 block drive, engine never even got warm). It will sounds like it's going to catch but doesn't. Definitely smell gas, but not gassy. More like spark issue. I checked the wires to the coil, all seemed fine. Have not done any work on the engine for weeks. Since it happened in a busy parking lot I couldn't tell if the pump was running. Got it started, drove home 3 blocks. Starts right up again no problem.

This isn't going to be cool at Watkins glen in two weeks. I need to figure this out.

I'm thinking it's wiring to the coil. God I hope it's not the fuel pump. Next time I will have to juice it with some fluid to see if it's fueling. I don't want to put my fuel pressure gauge back in there if I don't have to.

I’d pull the plugs and see what they tell you. I had a flaky injector and I did a lot of trouble shooting before I figured it out. It seem to work and then not work. You should be able to see if something isn’t firing right from the plugs. Also trouble check that your plug wires don’t have a flaky connection.

Another possibility is the 123. I’m not sure what year you’re running but the way it fits down into the drive is something to check. There is an adjustable collar that has to be right/tight so the distributor doesn’t slip at all in there or pop up.

Good luck!
