Nope... they only inject fuel during the compression stroke of the engine. Thats how they were designed.

SOURCE: 87 firebird fuel pump

Remove the exhaust, drop the rear end, remove the fuel cap, and surrounding rubber flange. remove the two hanger straps (be sure to have fuel tank supported so it doesn't just fall out. Remove hoses/electrical connector. Pull tank out, and remove metal lock ring that holds fuel pump assembly in place. Remove fuel pump assembly. Installation is reverse of removal. I have had 7 of these cars, and am currently driving one now. If you have any other questions about it, please ask!

SOURCE: 1987 pontiac firebird, does anyone know how to fix dash lights.?

you have to take out the gauges, they will be on the back. In some cases you have to take apart most of the dash to get the instrument panel out, sometimes you can just take the trim off the instrument panel. I had to take apart most of my dash in my 86.

How can i change my 87 bronco II 2.9 L from fuel injected to carbureted ?

You'll need three things to get this done: An independent distributor that doesn't require a vehicle computer, and intake manifold with a bolt pattern that'll work with a carburetor, and a carburetor. Oh, and a low-pressure fuel pump (the high-pressure one in the tank has to GO). You'll have to figure out the gauge cluster or replace all the gauges that rely on the computer.

The swap itself is shockingly easy, once you have those three parts. It's all bolt-together, and suddenly your vehicle just got a LOT simpler and more intuitive to work on. The intake might be a little hard to find, unless that block was available in earlier years with a carburetor (in which case it's a shoo-in)... but even if you can't find an earlier intake, it may not be too hard to make an adapter plate that'd fit the carb.

You'll need to deal with connecting the low-pressure fuel pump to that tank. One approach is to take the high-pressure pump out of the tank, rip its guts out, and use it as a big pickup tube for the external low-pressure pump.

Me, I love carbureted vehicles. I'd rather have carbureted than injected ANY day.

1985 mustang 3.8 engine running way too rich

This an '85 Mustang with a 3.8 L v-6? Thought they only had the carbureted 4 cylinder , and a 302 v-8, possibly throttle body injected?

Check air delivery system, check timing, any trouble codes?

I have an 87 f350 with a 460 motor i want to swap the cab from a 1993 f150 with an inline six cyl how do i wire the coil, and starter up ??

your going to run into more hurdles than just the starter and coil.however the starter you can wire the cellinoid to the ignition and just run a power lead to your battery. the coil you can easily run to a standalone ignition system such as an msd or mallory setup. you may want to look into a painless wireing harness, you can find them online, they can make you anything you need and it will be a plug and play setup, no head scratching needed. and the underhood will look clean rather than a rats nest of unused wires and random wires running here and there.

Where is the fuel filter located on a Chevy Mark 3 Van 350 motor/20

If it is fuel injected, it is an inline filter found underneath, along the frame rail. If it is carbureted, it is screwed in the carburetor where the fuel line enters it (intake fuel filter nut)

Got an '87 firebird that has been pieced together, looks like 5.7L T.P.I. engine. How can I identify what motor it is for sure? thanks

Look at the fuel injector cover if its fuel injected on top most say it there, it will say 2.8L or 5.7L if it is a v6 (6 spark plug wires) chances are its a 2.8 if it has V8 (8 spark plug wires) more likely to be a 5.7. Check your ECM if its what came with that motor if it is the original GM part the number on it should be 1227165 if it is it should be 5.0 or 5.7 more likely the 5.7.
