NOPE, THEY SHOULD FILL UP WITH THE PUMP AUTOMATIC.
MMM. PUT THE SWITCH ON " NOT ALL THE WAY TO START " JUST WHEN THE DASH LIGHTS COME ON, WAIT A MINUTE WHILE THE PUMP FILL THE LINES, DO THIS TWO OR THREE TIMES AND THEN START IT AND SEE IF THIS WORKS. IF NOT LET ME KNOW

SOURCE: 2001 Ford Windstar runs rough.

remove the coil pack and look at bottom of it if it shows any cracks coil is bad very common on these vans if you have a noid light check for injector pulse on #4 if you have pulse and good blue spark most likely the injector is bad you have to remove upper plenum to get injectors out let me know how you make out

Sounds like you have an injector leaking. Have someone just cycle the key on and off to run the fuel pump but don't crank the engine. If you see fuel dripping from the injectors, unbolt the injector cover on the throttle body, remove the injectors and replace the orings around the injectors.

I have a F250, 5.0 1985 FUEL INJECTED Engine that will not start cold, why?


Bad coolant temp sensor. This part asks as choke on FI engines. Some older FI engines also have a cold start injector. Check to see if yours does.

82 corvette crossfire injection, engine cuts out, does this at any speed will not start again injectors spraying to much fuel.this problem is intermitent, car can run for up to 2 hours of highway running...


Please go to the crossfire injection forum to get some straight answers to the 82 corvette CFI system and how to troubleshoot it properly. There's a lot of misinformation given here, so much so, I don't know where to begin.

One thing is, the 82 corvette CFI does NOT have a MassAir Flow sensor system, it uses MAP and O2 mostly. The CTS sends a signal to the ECM telling it what the temp of the motor is and in turn the ECM controls the amount of fuel being dumped. On the older (orignal) CTS sensors, they have one wire and takes its ground from the threads. If any coorosion takes place, usually the CTS will report a cold engine and request lots of fuel.

To repair this issue, install one of the newer style CTS sensors that have two wires, one for signal and the other is ground.

Fuel pressure and vacuum leaks on any CFI motor play key roles. Set the FP to 14-15psi measured inbetween the TBs. The regulator is located on the rear TB and must be slightly moded to make it adjustable and can be done in a few minutes.

STARTING PROBLEM, WONT IDLE,BLACK SMOKE, ONCE STARTED IT SOUNDS ROGUTH


This problem is a bit more difficult to diagnose because half of your symptoms rule out half of the solutions. I would think the ISC control could be dirty or not working or your fuel injectors are sticking open.

With black exhaust smoke you are running rich. Often the "Cold start sequence" is at fault for poor starts making the engine too lean when the sequence fails. An intake air leak can cause the engine to run Rich, causing the black smoke, rough idle, rough running conditions. This is still a possibility, but the on-board computer usually sets a Code saying you are running "Lean" and then enriches the fuel ratio and floods the engine by itself.

Now the fuel injectors can cause several of your problems. For start-up problems, the remaining fuel pressure can dump fuel into the engine as the car sits because the injectors are sticking open. Someone would need to perform a fuel pressure bleed-down test to see if you have this problem.

Another way to verify this problem is to capture the oil during an oil change and smell it for gasoline fumes. The dilution of the oil will destroy the engine. If the injectors are found to be the problem, a new oil filter and change are needed.

I'm having a problem. I have an 84 mustang gt


The 1984 model could be throttle body injected or a regular 4 barrel carb. The GT model is supposed to have a carb.
CFI is central fuel injection which is like TBI. The throttle body has two injectors mounted in the center, one for each bank.
If it has a carb you may have some adjustments you can make. If it is fuel injected you don't. The computer monitors the engine temp and exhaust gas to regulate fuel mixture.

1995 f-350 runs rich and won't idle?


If this is a gas engine, check for air leaks on the intake manifold and every vacuum line and switch you see. Use a pump spray water bottle and with the engine running, spray around seams and such.

A change in rpm or stalling will indicate the leak.

What is probably happening is the air leak is making the system run rich to balance the air/fuel ratio. This would make more fuel dump into the engine where it is not needed.

Another possibility is a loss of the signal from an O2 sensor. The O2 sensor sends a signal to the ECM to set the fuel demands and let the engine controls know that the fuel ratio is rich-normal-lean to adjust to optimum running condition.

Now if this is a Diesel, the hard to start condition would be due to an inoperative glowplug timer or worn glowplugs. If this is the mechanically injected model, the injector pump is timed to get the fuel into the cylinder either earlier or later to change the fuel ratio. Your diesel injector pump would need to be retimed. It will help across the board.

Please rate my info and let me know how you solved this.

Fuel Injection Problem


Is your cat. convertor blocking up? If it is this condition, it could very well be the problem. Disconnect the convertor start the car & see if it takes the gas well. If it does, change the cat. convertor. Good luck!

Runs rough at start up,then runs okay, Hesitiates momentarily when moving from a stopped position. Occasionally wont start and runs rough, then runs okay. This problem is intermittent


you have a bad injector, if you have A... as it states on the top of the motor 2.8, 3.1 L MULTI PORT and dies or idles really rough and the exhaust smells like strong gas. most likely you have an injector that has shorted or is shorting out and from my experiences usually after a road trip or using fuel injector cleaner or buying a used car. it will cause half the motor to not run or run poorly VERY POORLY or even burn out 1 injector fuse out of 2 under hard acceleration or idles but as soon as you touch the gas pedal dies. but only if it is a MULTI PORT fuel injected motor. ive heard you want to try and replace them with bosch injectors out of a 2.9l ford bronco/ranger. only attempt if you got the mechanical know how sometimes if not done right will leak gas because of the injectors being kinda different length. research before attempting.
