GSL-SE Ignition Problem ???
 

Maybe someone has seen this before. The car will start and run, but after a while, it lags when accelerating to the point of stalling out. Shut off the car for a couple minutes, then it will be fine. I noticed when it does this, the oil pressure gauge reads zero. Could it be trailing coil? Maybe bad igniter? Maybe even a bad fuel pump?

Any thoughts or suggestions appreciated.

start with the fuel filter.

Its new. Tank was dropped and flushed, screens cleaned, lines cleared.

well, was it behaving this way before you had the tank cleaned?

if you're convinced that the filter (regardless if it's new) is not the issue, then move on to the pump.

The car sat for five years with a dead engine, but everything was working fine when the engine blew. Different engine now. Yes, will do volume and pressure test next

Pressure around 50 psi, but volume was less than half a quart in 30 seconds. Time for a new pump? What is the best direct replacement for the stock pump?

.just for kicks...how is the voltage when this all happens?..

Voltage is fine, no issues there.

New Fuel Pump solved the problem, now on to other issues!
