Car turns over but has no injector pulse. I can make it run by spraying fuel into the intake tube. After a min it gains injector pulse and runs fine. If i shut of for a real short period it will restart fine but if i leave it off for a few minutes it will loose injector pulse again. Does anyone have any ideas? I have only two codes while running a tps and a engine coolant sensor. I fixed the coolant sensor and ohm the tps and it showed to be fine. Please help me thanks.
