I've been trying to get my 91 running off and on for a few months. It runs nice when it's cold but after a couple of miles /10 minutes it just dies. The only way I can get it back home is by flipping the ignition and it'll surge, then cut out. I have to do that the rest of the way back home. I've replaced both fuel pumps, pump relay, air filter and cleaned the MAF.
I'm planning on checking the injectors next but will it run off the cold start injector until it warms up? It seems like it runs fine until it hits that point. I've picked up a fuel pressure gauge and will check it at the fuel rail over the weekend. Any suggestions?
