So i have a 87 t4r sr5. i just replaced the head on it. got it to start and run for about 45 seconds. i can't get it to idle. and now i can't get it to start. i have good compression, spark, ect.... Im thinking that my fuel pump has gone out. if i let it sit over night then try to start it again, it will run for about 30 seconds. I tryed starting it today. i wouldnt go. then i replaced the fuel filter. it ran for a few seconds with my foot in it. and now nothing. let me give you a little back story on this runner. its an 87, it has 320 thousand miles on it. this is like the third engine. i has been sitting since 2007 with a full tank of fuel in it. im thinking the fuel is the problem. any suggestions?
