I installed a raptor 150 on my 01 work truck. install went great but the truck loses its prime and bogs out and dies. to get the truck to start I have to bleed the injectors. is it possible its getting air in the system? all connections seem good. the pump runs for a second when the key is turned and then when you bump the starter it will run for about 5 seconds. Please help I need my work truck back on the road thanks...

How much fuel in tank? using a draw straw?

Using stock pickup? Did you clean the screen on the pickup in tank? Are you using a relay to power the pump? Power and grounds are good? Using a test light do you have power to pump engine running or can you hear pump running?

I wasn't aware there was a screen, they is a relay built into the harness. It's hard to tell if the pump is running when the truck is on I will check with a test light. Once the truck is started it will bog out and die at idle but when you rev it up it won't die

Ok, here's the 64,000 dollar question, do you have a fuel pressure gauge, and if not, how quickly can you get one on to make sure your pressures are correct?
