I believe its the fuel pump or maybe the filter in the tank.. Struggled to get to 30psi but when it did it started and then went to 60psi..

I got no smoke coming from the exhaust.. When i first started tracking this down i had the fuel rail off and hooked up and primed and the fuel injectors were all dry

The regulator,filter and pump is all in the fuel pump module on mine.. Hasnt started hard since i hooked the gauge up even though the pressure drops to 0 but i still got it hooked up and peaking out of the hood so i keep an eye on it..

Been chasing a intimate extended start problem.. Well I made an adapter to fit my fuel rail so i can test fuel pressure..i took a video of the gauge and im going to try to post it.. Some times the key has to turn twice to hit 60psi but will immediately drop to 0.. Starting will climb to 60psi and stay at 60 while running and drop to 58psi when hit the gas but go right back to 60psi but when i shut the car off it will again immediately drop to 0psi. Is this normal or should it hold pressure? 20210304_164212(1)(1).mp4

I also unplugged the crank sensor and it still started but did take longer before it did so the crank sensor on this doesnt work they way i thought... Would be nice if it was just the crank sensor delaying the signal to the pcm. If the sensor is bad wouldnt it set off the engine light?

Well my extended crank is still there.. I did verify that the pump does kick on the way it should. I have a new o2 sensor im going to install and the short runner valve is on its way so once those are installed that should take care of my 2 codes.. I also got a new crank sensor im gonna try too. Will post my results once everything is installed

I already had everything needed to do the repair.. All thats needed it a 12v 4 prong relay, some wire, wire connectors, solder and iron and heat shrink. But they do sell the kits for them.. Also sell the bypass wires to but thats only to turn the pump on so it can be tested

Got it all wired up...instructions came from mopar them self.. Very simple and easy to do. I already had everything so it was easier for me.. This also isnt a temporary fix. Its what mopar came out with as a cheap option to permanently bypass the internal fuel pump relay.. I started the car about 25 or more times in 2 days and also drove 100 miles. Starts up on a dime and fuel pump kicks on every time the key is turned on. Im going to attach the pdf file so if this will help any one feel free to down load it.. Also will try to update the title to fuel pump relay fix... Thanks alot for your help guys.. S1308000399.pdf

I made a external relay set up i got from the web. Going to wire it up today and if it cures it then later down the road im going to send my tipm to get the relays replaced

I just took the tipm all apart and it actually looked very clean.no corrosion or burn marks any where on the pins or board. P0133 and p1004 are the codes i get.

It is the 09 so im guessing it is the tipm seems i got the intimate fuel pump issue

I don't have that code

Vehicles i worked on the crankshaft position sensor only controlled the spark not the fuel pump.. Fuel pumps would prime when key on and constantly run when cranking and running. On the journey what all controls the fuel pump prime? Pump is working when cranking and running just not all the time on prime

When it starts it runs fine.. No skip, hesitation or nothing. The extended crank will happen when car is cold or hot. Theres no Schrader valve so i cant put my gauge on it. The instant restarts seem fine.. Sometimes when i shut it off and wait a few minutes then restart its extended but sometimes its quick.

And im in south Georgia so its not cold.. Also just replaced the battery and alternator due to what i though was a charging issue but ended up being the starter so i replaced that to.
