Search Results for ‘fuel injection’

After toying with the factory Carter BBD for more than what it’s worth, and trying to get the well received Chinese copy to work was the final straw for me. Ever since I got the Jeep back in September 2021, I knew I was going to covert it to fuel injection. The last time I tinkered with a “CJ”...

I have a 1975 cj5 with a 304v8. It recently started running really rough and then finally quit. No spark but has fuel going to carb. I followed the manual troubleshooting procedure till I got to the part about using a pulse simulator (which I don't have). Other forums suggest that there is...

Good day to all those with great taste in cars. Seeking help from some diagnostic wizards for fuel flow and starting issues. I need a help diagnosing jeep xj 1996 4.0L 6 inline MPI problems, because there are too many parts i could potentially try repair. Main issues: On starting the car...

So I've been looking for info online and there is a lot of conflict so I was hoping to get more info here 89 YJ, originally with the 4.2L. Did the HO swap and now it's fuel injected with an inline pump near the tank. The problem is that during hot summer months it occasionally vapor locks and...

I've had my 2000 XJ for five years now. I've recently invested a lot into it to try and make sure it keeps running great for another five plus years. I hadn't changed the spark plugs since I got it, so I knew I was overdue for that. I was also pretty sure the injectors were stock, and I...

I'm planning on pulling and rebuilding my 304 out of my 79 CJ-5 and was planning on installing Edelbrock's new ProFlo4 multi-port injection system. I see they're finally on the market and was trying to see if anyone has purchased one yet. Thoughts? Thanks

Does anyone have any suggestions on installing the PCM from a Mopar MFI kit? The instructions say on the firewall above the evap canister. But between the height of the evap canister making the top screws on the PCM even with the lower lip of the wiring harness opening, and the size of the...

Our 2005 Liberty with V-6 with 88k miles is experiencing starting problems. We do a lot of shut down and restarts. It frequently will chug some and not start. If I turn the key off and then try again it will usually restart. Then it sometimes runs rough for awhile. Twice it was very...

Hi everyone. I am starting to plan my winter Jeep Project(s) and I was hoping for some advice/counsel/whatever on two separate projects. 1. There is a squeak which seems to be coming right from my water pump. It is not the belt. I have tried every type of tightness on the alternator belt know...

Hey Guys: I upgraded my Grand Cherokee Laredo 4.0 by incresing the size of the throtle body (BBK) added bOSCH three port fuel injectors and randomly is giving me missfires everywhere. I noticed that the connectors for the Fuel injectors do not fit right and I had to hold them down with zip...

I have a 90 manual wrangler with a 4.2, I recently did the head swap and fuel injection using parts from a 4.0 Cherokee. After doing the swap, I was able to get the jeep running, but only without the alternator fuse in. When I would put the alternator fuse in the pdc, the jeep would start, but...

I own a 1989 YJ and the previous owner put a fuel injection conversion on it. I have a couple of questions about this: Is it possible that it still has the original MCU under the dash and a new model computer and ECM mounted to the firewall on the driver's side? I am having trouble with the...

Hey Everyone, Here the background... I have the MOPAR MPFI kit on my 4.2 Recently discovered that the wiring harness was badly burned (to close to exhaust.) I replaced the wiring harness and computer. Engine runs now, but sometimes, it feels as if a cylinder just drops out... One thing...

Hello, after a about 6 months of screwing around with the stealerships, and going through any posible forum that may help me. I've decided to ask for your opinions. It started in December 2013, i got home from the airport after leaving my 2008 CRD GC for two weeks, it would just turn over at...

:confused: Ok, so the Jeep has been back at the shop that put the motor in for a while now. They swapped out the blown AMC 360 with a newly rebuilt AMC 304 bored over 30. All outside parts were still good and were swapped out. Oil pump was rebuilt inside out. I drove the Jeep home with no...

Hey guys, I'm new to the forum and hope to become a regular! I drive an 89 4 banger and am having some starting troubles. I have found that the seals on my TBI Injector are very worn, so much so that fuel seems to flow out of the top of the injector when I crank the engine. My question is...
