Need some help

[Barnbuilder]

Tuesday I left the fire station and made several stops on the way home. Truck took 2-4 trys to start and was low on power. Truck starts fine now but still low on power. Fuel pressure is 65. Acts like its not getting fuel. Push the go pedal and it takes forever to accelerate and it doesn't have any smoke out the exhaust like it did before when I would lug it and try to accelerate. Which is nice. Its a 6 speed. I can only get 18 psi of boost in the hot tune.

Unplugged ICP sensor and there was no oil in it. Truck seemed to run better with the ICP unplugged but the idle was off.

For a little while I thought the SRP1 was going out again. When it went out 3 years ago truck was hard to start and then just wouldn't start. Had SRP1 rebuilt and new IPR. 29k miles since that happened.

Last year I put AC injectors and a 38R on it.

Any thoughts? I have to find someone to pull codes. No lights on on dash.

find codes like yous said.. what is hpo holding? icp dc? even if those where off it would smoke worse but who knows. hows battery voltage and alternator voltage?

Haven't checked voltage but batteries and alternator were replaced in Dec. Tues. when I get home I'll kook my cauge up on the heasds and see what kind of pressure I'm getting.

huh? I thought that when you unplug it and there is no change in idle, it is already running in default and needs changed qnd if you unplug it and idle changes, then its working properly cuz it forces the default program hence the change in idle?

If it ran better with it unplugged, something is not right. If it has oil in it, something is not right.

After I get off the pedal, when I've been into it, it lopes like its trying to catch up. Then it smoothed out.
Has a melling lpop. Have an oil leak that i assumed was at front of pan. But I guess it could be from lpop. But if that was leaking down it would be hard to start wouldn't it?

When I try to accelerate its like it revs up and tries but not getting the fuel it needs.

Hooked it up to the computer and it looks like the SRP 1 is going out again.

Put an Adrenaline in yesterday with a new IPR runs better than it did with the srp. Wonder if there is any crap in the injectors. Still has a lope after I've been on it hard like its trying to catch up. Might unplug the icp and see how it runs.

 

[Arisley]

You will be happy with the Adrenaline. The one on my truck has over 100K miles on it and still runs strong.

I was in the test group. Supposed to run it for a couple weeks and send it to the next guy. I ran it for twenty minutes, called Bob and told him he was going to have to send another one to the next guy in line, I was keeping it. He laughed and told me that was what everybody had done to that point.

Tried to drive it with the ICP unplugged. Made it to the stop sign and the idle was so bad I plugged it back in. Like it was running on half the injectors. ICP sensor cost has really increased and hate to buy one if i don't need it.

Sucks that the SRP1 is so moddified that they won't take it as a core. Then when I got the Adrenaline had to go to Ford to get the Quick connect fittings for $70.

I believe it.

I know you prolly needed it in a pinch but you could have had them overnighted from riffraff or dieselorings.com for less..

Yes. We left for the mountains yesterday morning pulling the tool trailer. The rearend didn't like coming up the driveway to customer's house. Popping bad. Needs to be rebuilt. Had to use 4L on part of it.
