Question
my truck dose not get any spark or gas there is 13 psi in the fule lines i have bot a new coil 1988 350 tbi

Answer
Hello Forest,
13 PSI is great. But you need a pulse to the injectors.
The ecm controls that, as well as the spark, so that could be what you need, but I would sure check power to the ecm first. Look for a fuse marked ecm or ign.

There is a crank sensor that tells the ecm when to inject and spark. I believe it is in the distributor, but check the fuses first.

I have been maintaining a fleet of approximately 55 light, medium and heavy vehicles for over 20 years. Most are 4X4 pickups and off road fire fighting trucks. Some medium duty trucks. Some military light trucks. I can answer most questions concerning 4X4 engine, drive line, suspension, electrical, and fuel, both diesel and gasoline. Ford, GM, and Dodge, old and new, but prefferably not newer than 99.
