1989 ford e 150 fuel poblem

Had a 89 cavalier did that start then die it map sensor. Also check ground wires if the become too corroded they won't start sometimes just run weird

Check for vacuum leaks eg. PVC hose power booster and hoses around manifold area.

if the fuel lines have any rubber fuel lines they could be sucking air. also try replacing the fuel caps, it may not be venting

could be your coil is bad when it heats up it shorts out.

check for restricted or stopped up catalytic converter.

Most likely the fuel pump,when the fuel filter gets that restricted,it most of the time,is not long before the fuel pump goes out,because of the strain on the pump.

If the battery is strong and charged, starter is fine, car ran okay while getting progressively worse until it died and won't restart now, might be fuel filter or pump. I've dealt with two cars with fuel filter issues. Both would idle fine, but run progessively worse under load and eventually die and not start although everything else checked out. Engine turned fast enought to start, battery strong, alternator fine, air cleaner clean, all that. No start. Changed fuel filters and done. Everything back to normal. Both cars were about model year 1990 (1989 and 1991). Replaced one in a parking lot and car fired right back up and powered on home just fine, whereas the week leading up to it it ran worse and worse, hesitated on acceleration and finally would die if you hit the gas. Fuel filter may be in engine compartment. Looks like a canister with an in and an out for fuel. Pump is in gas tank and is way more work and money. Good luck, hope this helps.

your fuel pump may be working but a certain amount of pressure is required to maintain proper flow of fuel ....a few places will do a fuel pressure test for you for free such as a parts store to help you determine if proper fuel pressure is present ...

U are going to have to replace the fuel pump, the pump is located in the fuel tank.

fuel pump,or bad ecm, or bad coil or coil wire
