well got new battery in now its stumbleing all the time while your driving and when you stop. One time it felt like it was stuck in overdrive and i was trying to take off it just had no power! It has 150,000 miles on it

 

check fuel pressure i think you need a fuel pump

 

Check the battery connections. Probably not tight. Triple tighten the positive side.

If they are, with your 0601 code, probably need to reset the PCM with all the issues it had via the low batt voltage.

Disconnect the NEG batt cable completely. Place key in ignition and turn to start, holding the key in the on/start position as if it was cranking over for a duration of 10 seconds. Turn key off. Repeat two more times. Reconnect the NEG cable very tightly.

Drive 100 miles allowing the PCM to relearn and let us know how it is acting thereafter.

It could also be a TPS but I'm thinking a connection. Now a P0601 means a bad PCM however I'm thinking it's more of a connection issue. Also check the negative grounding lug and cab to block grounding lugs.

 

i reset the computer it ran much better only acted up abt 3 times in 25 miles thats much better. while i was checking the engine i walked behind the car and heard the fuel pump running it was very loud i have never heard it running like this before or just never payed attention. could the fuel pump be related?

 

Get a fuel pump pressure gauge. Cheep at you local parts store. Now I need some one to tell us what the pressures should be. I think it should be about 50 psi. Also make sure it holds the pressure after you tune the engine off.

 

If fuel related, it would be always having a problem and would not have gotten any better with the PCM reset.

The PCM will learn the current sensor data and adjust accordingly. Check in at the 100 mile mark or so.

Well a very loud fuel pump is a problem in it's self. However Indy is right is saying a PCM reset doesn't do anything to the pump.


Second issue sounds like a PCM if you through a P0601. That code means the PCM is going out the door. You can get a new one that is pre-flashed from ebay. Make sure they know your year, motor, VIN and mileage before they ship it to you. Also ensure the year and motor when bidding or go straight to their store. I would stick with a company that is 100%. They sell for about $200 shipped for direct install. But I would only do this if you have exhausted the battery connections on all 4 sides of the cables.

 

i did another reset and so far so good drove abt 25 miles or so and no problems yey but tomorrow will its first big trip out to check.
