To start this is a 420a question. So I rebuilt my 420a put it in started it ran fine but since I was an idiot I forgot rear main seal (making only ran for 5 to 7 seconds). I took tyranny out put in seal, trannies back on now it wont do more the rev took about 1500 and died. I am getting tps code map code and low 5 volt power supply code.I checked voltage in at both spots and they show 4.88 at one and 4.94 at other I can't remember which is which. So I tried spraying gas in throttle body and it will run like this so I check fuel lines they have flow but I have pressure gauge. What's stock fuel pressure. So I gave up today just wondering if anyone can give me somewhere to go.
