Hey all, coming in to see if anyone has some esoteric knowledge about the difference between the EFI gas tanks. General online consensus (LMR, Ebay, some forms) is that all EFI tanks from 83-97 are the same, so many gas tanks out there rated for all 83-97 cars. Even LMRs little diagram says...

2006 GT manual, 210k miles. I'm having an issue, mostly once the engine is warm, where I have a misfire/sputtering below about 2500-3000 rpms. No codes. Once the car gets hot, if I drive it for about an hour, it will hard start. I installed a new fuel pump. Upgraded said fuel pump. New throttle...

Hey guys I have a 1986 5.0 (with efi). Anyways i bought the car with the issue of it running rich and I'm still having that issue. Come to find out its pushing 55 psi of fuel pressure at the rail. The car currently has stock injectors but I found 30lb/hr injectors in the back of the car. Long...

Simple question, should I see a priming pulse on injector 1 using noid light at key on with engine cold? Trying to resolve a cold start issue, will not start without starter fluid. 2-3 rounds of this and it will start to run on its own, and once warm will restart normally. Noid light on...

I was going to work this morning and the car lossed power and stalled, happened once before. Tried to crank right after but nothing. Waited a minute, fires right back up drives fine. Could this be a fuel issue somewhere?

Hello, all! I am new to these forums, and forums in general. I have recently purchased a 1990 Vert, it is my first Fox Body 'Stang. I am troubleshooting the electrical side of the fuel system. I got the car with a "bent rim" (lol no, it was the axle) and a few other "minor problems". After...

So recently i got a 1974 Ford Mustang and so i realised fuel isn't going to the carb so i decided i got a new gas tank. fuel filter. and fuel pump but i tried cranking her over again and no gas is going to the carb, before you guys ask yes i have about 2 gallons in the tank. just any advice on...

Yesterday my 93 fox was running like it has no fuel and it has fuel. Today was when I drive it was all good. The first day I buy it did the same thing

Hey guys I have a 92 mustang it’s been modified a bit edelbrock performer intake e cam I’ll take it for a little drive and it’ll pretty much install start trying to die I took it down the road today and back when it started acting up I hooked a fuel pressure gauge up and it had dropped down to...

Car died on me while driving. I could hear my pump starving for fuel (Gauge read 1/4 tank). Had a buddy bring me some gas, car fired right up. I went to fill up and after 9.6 gallons the tank was full (including what I put in on the side of the road). This means my tank should've had around 6...

Hey guys I have a a 2002 mustang gt. it’s FBO WITH TRICKFLOW STAGE 2 CAMS. Dyno tuned. I’m running into some fuel problems I guess and with that code I also have a random misfire which is P0300. I’m hoping to see if the p1237 code is the reason why I’m misfiring. Already did spark plugs with...

What is the hole for above the fuel pump hole. What goes there

I’m buying a fuel tank kit for my 1990 foxbody and it comes with a 255lph fuel pump which is to big for my foxbodyand comes with a bracket can I buy a 190lph fuel pump and use the same bracket from the 255lph

Hello all, I am in the process of recording datalogs for my tuner to get my Mach 1 dialed in. The base tune is dialed in according to my tuner, so he requested some 3rd gear 2,000 to 5,000 rpm pulls. On the first pull at WOT it felt like I hit the rev limiter at ~5,000 rpm. I am not sure if it...

Hello everyone, Here’s my issue and some backstory on why I started troubleshooting. So my 2004 Mach 1 will never start the first try. But it will start the second. I’ve changed the battery, I needed to anyways so I’m not sweating over the battery change. The fuel pump is new. It’s a Walbro...

Hello everyone, So I purchased a 2004 Mach 1 with 90,000 miles that needed some work about a month ago. I've been slowly working on my list of things to fix or repair on the car. It ran great when I took it for a test drive. Drove it for about an hour before I decided to take it home. I was...

I have 1990 mustang gt and I'll be driving and everything is okay but let's say I'm in 5th gear if I go into neutral to coast the rpm rise to 3k, sometimes even stalls. I bought a new iac and fuel filter and I haven't stalled YET but I haven't drove it much , but it's still rising in rpm to 3k...

1987 5.0 Manual, timing chain broke after I finally had it running well Rebuilt with an upgraded cam. Original heads with a valve kit. Gear driven timing. Newer explorer intake Harness and A9L computer out of an 89 for the MAF conversion. EGR deleted since it has a newer explorer intake. All...

So I have an '85 Mustang GT with a 302 automatic and 3:73 gears. I replaced the engine with a roller motor I purchased from Blueprint Engines. The dyno sheet that came with the engine showed 9:1 compression, 308 hp and 344 ft/lb torque (at the crank). I put a Holley 4160 600cfm with vacuum...

I know this is one of the more common issues with these cars, but it’s driving me absolutely crazy lately. I rebuilt my 302 about 5 years ago, using the gt40p setup. The car runs flawless when I do drive it, which is maybe once a month. Within the last 6 months though there is a noticeable...
