Hello! my friend has a 95 blazer with a cutting out issue. It started out as happening once and a while and slowly got worse. the engine cuts out, not just a single cylinder miss. Sometimes it will run and cut out going down the road and eventually go into a fit and quit. Other times it wont even start, let it sit for a day or sometimes an hour and it will start. What has been replaced:

CAP AND ROTOR
PICKUP COIL
UPSTREAM 02 SENSOR (ONLY TROUBLE CODE)

I tested the fuel pressure, 60 psi and runs at about 58. After starting and shutting off the fuel pressure lost maybe 1 lb after 2 minutes (could be the fitting on the service port, couldn't get my fingers in there very good). Ignition does not seem to be the issue, it seems to be loosing fuel at the injectors.

Could the ecm be failing? it does have a reman in it now (replaced by previous owner). Could the cpi be bad (wouldn't it leak down)? it has the obd 1.5 (obd I on the tag but obdII connector).

Please help!!! and thank you blazer forum for all my researched info!
