If you are using some sort of rigged up and leaky tester as you have mentioned, you are pretty much wasting your time because without positive results the test in itself and the results from it become invalid. Many parts stores have a loaner program for tools like that where you only need to put down a deposit that you get back when you return it. Look into it. You can't trust test results from some tool that was rigged up to the point you yourself have to estimate what it may or may not have shown.

Wow,
Best to call the junk yard I guess. if I replace everything out of spec on this truck, I'll have paid twice the price of a new truck. LOL

Sport - with untrusted info all bets off. Accurate fuel pressure. Accurate voltage even if starter cranks taken while cranking and watching fuel pressure.


You thought battery had nothing to do with the plow well Fisher isolates just lighting and power to the plow pump if not attached can't do anything can it, so as not to duplicate but it's using the truck's battery and charging system. Low voltage delivery trashes things, especially if it spikes or drops electric motors take a hit. Mopars and any maker don't like that.


Multiple attempts you add flooding into the game and you'll never get all the ducks in a row.


No harm meant but if you don't have accurate testing you are wasting time and money,

If you have a better system, you should advise the engineers that they are wrong.

Finally got a chance to work on it again.
Had to remove broken spark plugs.
My fuel pump Pressure tester wasn't doing the job so had to buy a newer one for efi.
Pressure was dropping off. Problem was that after changing out the old fuel the pump wasn't picking up the fuel right away. Needed quite a bit of fuel to pick it up properly. All good now, running great! Initial problem was indeed the old fuel I'm guessing.


Thanks for the help!

Sorry it took so long for you but seems you are all set now and can consider this case solved so will lock it to keep the spammers out. You can re-open it by request from any moderator upon request,

So, it was the fuel pressure after all. They have specs for a reason.
