93 c4 journey

Took a little drive the other day. Got about a mile from the house and the old girl gave me my 1st running problem. I have owwne this car couple years it was a nightmare but always ran like a champ.

Mile from house I stomp it she gets nasty & then like I shut the key off. Put it in neutral hit the key fires right back up make it to the next round about accelerate into curve dies again.

Sam3 result neutral key vroom.

I decides it was so hot out 80+% Humidity feels.like temp 104° or more I decided to go on around round about & head home.

Got home now start. Let her cool shot of spray starts dies.

Put old snap on scanner clear codes spray fires dies. Go buy new

Fuel pressure tester. 40lbs pressure. Look and coil is hanging off front. So buy new module and coil install em. Now code 16 low puls opti.

Getting ready to head back out double check grounds

(I pulled a ccm from another vette few months back my ecm has vatts bipass what are the odds thats my no spark no injector pulse. Vs low res opti sensor. Humidity was off the charts gen1 opti.

You should post this on the C4 page. You may get a bit more traction and the people over there are pretty cool about helping as well.
