Ford Fuel System :: 1994 - 4 Injectors Do Not Pulse

I have a f53 motorhome and 4 out of the 8 injectors pulse. The front 2 and the back 2 don't pulse. The middle 2 on both sides work perfect. Why would they not pulse and only give out positive on the two wires to the injector on the one that don't work. The ones that work they pulse.

Ford Fuel System :: 1990 E250 - Fuel Shutoff Switch Not Activated?

My '90 E250, open road, mini motorhome , says on the radiator mount , that there is a Fuel shutoff switch that may have been activated.... I don't have the manual for it, so I need finding the switch, so I can reset it ....The vehicle sometimes starts after about 2 mins with the ignition on, but today won't start, even after a longer wait. Both tanks are full...Fuel gauge not working , in either front or rear position. I can hear the rear pump,in the tank, but can not hear the front one....When I bought it last year, it ran fine after waiting to start, and both positions worked , no stalling , or shutdown.Came home about 95 miles, and it's been parked almost all the time since. I want to start it up weekly , but am having that same problem ...Today was the first time I could see the Fuel Pump Shutoff warning ...but can 't find the darn switch to try resetting .....

Ford Fuel System :: 1990 F150 Truck Takes A While To Start Up

My truck is a 1990 Ford F150. It seems like when I let it sit for a few min that the gas just drains back into the tank and there for it wont start up that fast, it takes a while to get it going but when I shut it off and start it back up its like a new truck. It starts right up!!! Any tips on what might be wrong, maybe the gas cap is letting pressure out? Im 17 and my dad knows alot about trucks but he cant tell whats wrong.

Lumina :: 92 Chevy Euro Has Spark But No Injector Pulse

Was called today to look at a car that wont start its a 92 Chevy lumina euro with the 3.1 v6 automatic 4 door. The car has a new crank sensor recently installed ran well for a while and now has no injector pulse. Checked for spark its good. sprayed starting fluid in the intake and it fired for a second acted like it wanted to run and then died. Checked for fuel at Schroeder valve it has fuel there I don't have a fuel pressure gauge but it sprayed pretty good. I'm not real good with electrical but thought maybe the ICM under the coil packs could be bad I have one off a running engine on my shelf but wanted to see what other people had to say first.

Ford Fuel System :: 1990 Aerostar - Gas Dripping Onto Exhaust At Y-joint And Evaporating

I have a 1990 Aerostar 4WD, 4L, with about 120k miles. About 6 months ago I started my van and noticed under it that gas was dripping onto the exhaust at the Y-joint and evaporating. I shut off the van and drove another car to work. That evening with fire extinguisher at hand I drove my car up on ramps and quickly got under it looking for the leak. NOTHING. 6 months later...yesterday. I drove for a few blocks from home and notice heavy gas fumes etc. Stopped the van and again gas was dripping onto the Y-pipe joint.

This was an explosive situation... I pulled off the doghouse cover and saw, smelled and touched gas friom on the right top of the engine near the back. My questions are: What could randomly be leaking at this location and is it fixable without pulling the engine. I pushed the van to a secure location and am afraid to turn it on. Maybe I will drain the gas tank before then. I am just now trying to find the schematics for the fuel line delivery stuff. Where to go for a manual.

Volvo :: 740GL - Weakening Of Injector Pulse (Ground Side)

My friend like to get his 1990 740GL back on the road. It starts and dies. Narrowed it down to injector pulse. Noid light is bright the first couple pulses then gets weaker and weaker while cranking to almost nothing. Tried a new radio suppression relay.

Tested the voltage to the positive side of the injector plug and it is full voltage with no drop from battery voltage. I tested the negative side of the injector plug for resistance to pin 19 on the ECU and it was perfect no resistance. I thought that was a pretty good sign the ECU was bad. Replaced it. Jetronic and same exact number. Same exact symptoms. I checked the grounds on the valve cover to firewall and the ground on the intake from the harness.

What else could it be?The ECU I replaced is in the passengers kick panel. Is there another computer for the injectors?

I am experiencing a power/boost pulse when under moderate to heavy acceleration. I'm wondering if this is a sign of my diverter valve failing or another issue withing the turbo system.

Ford Exhaust System :: 351w Exhaust Collector Stud Nut Size

I have a 90 bronco with a efi 351w and im missing one nut for the manifold to exhaust pipe flange.

Ford 6.0L Power Stroke Diesel :: Fuel Injector Replacement

My 2005 F-250 does not have power when the engine is cold. When the engine warms up then it seems fine. I believe that the fuel injectors need replacement. I was told that one cannot get new injectors. They are all re-manufactured. Is this correct?

Ford 6.0L Power Stroke Diesel :: Fuel Injector 8 Replacement

I may have to replace fuel injector #8 on my 2004 6.0. Aside from doing brakes and rotors, I don't have any experience working on my truck.

Side note- this is the second injector to go bad in the past few months. Ford also wanted to replace the HFCM, so I'll be doing that as well.

Ford 6.7L Power Stroke Diesel :: Misfire - Smoke - Fuel Injector Supply Line?

Went to go and start my truck this morning and noticed after it was running that it sounded like a misfire, then i seen the smoke... I shut the truck down and lifted the hood and seen that somehow i had a high pressure fuel injector supply line on the Lh side break off. The line that goes from the fuel rail to the injector port on the valve cover (theres 4 of them on a side). There doesn't seem to be an o-ring or anything on them, they are just pressed over and tighten down.
