i recently baught a 91 dx sedan dpfi and was planning on fixing to sell.i replaced the head gasket and valves that had ben messed up.i put motor back together and cleaned tank and fuel lines.now wen i try to crank it it just keeps turning over but wont start.and wen i crank it and sray fuel n carb cleaner into the throttle body it will crank up and stay runnnin as long as the carb cleaner is being sprayed???motor sounds good but wont run without the carb n fuel cleaner....any ideas????and the fuel relay is coming on and i no im getn fuel to the intake manifold.-

 

FUEL PUMP MAYBE?

 

i found out that the green injector was bad on the bottom...put some off another motor i got and fired rite up.....damn dpfi....thanks tho
