Anyone know how to check to see if I have fuel pressure or if my fuel pump is working in my 88 GXL? I really need to get this fixed ASAP. Please be pretty detailed as I am not close to bein a mechanic. Thanks.

Come on guys, I only have tomorrow to look at my car to see so I can fix it this weekend. Help....

Ok. Look at this url.http://www.rhichome.bnl.gov/People/s...ke_removed.jpg It should show a picture of the secondary fuel rail. The fuel rail is that metal tube about seven or eight inches long. In the picture you'll see that on the front end there is a light yellow piece of plastic. Its the other end that you're interested in. It has what is called a banjo bolt. It is I think a 19mm bolt. Keep this in mind. The first thing is to turn the key to to on position(do not start the engine, just to the on position. Now go to the engine bay. On the right hand shock strut tower, to the front of it and inboard you wil find a yellow electrical connector with two wires in it. It is not connected to a thing. It is hanging in mid air. Get a piece of wire and jumper the two wires together. You should have heard a click when you did this from a relay. Doing that energized the fuel pump. Now take the 19mm wrench and slightly loosen the afore mentioned banjo bolt. Did it spray fuel when you loosened it? If it did the pump is working. How well is another thing. Why are you asking about the fuel Pump anyway?

I'm askin cuz I don't know what else it could be. I changed plugs, wires, fuel filter, had the alternator checked & now checked the coils. Can't seem to figure it out. Any ideas would be great. I figure its the fuel pump or the ecu. Thanks.

A better way to check PF is to get it checked professionally. You can check to see if its pumping by removing the rubber line comming from the filer on the driverside, and pumping it into a container.

Somewhere I'm missing your drift. Are you saying that the car will not start and you think its the lack of fuel? I don't know what PF is. If you are serious about checking to see if the fuel pressure is adequate just go down to the PEP BOYS and buy a fuel pressure gauge, download the factory manual from http://www.iluvmyrx7.com, go to section 4a and follow the procedure and the results. You can put tee in the pressure line off the filter or make a fitting from an old banjo bolt that will simulate the tool in the manual. Not a high tech thing to do. If I'm reading you right and you think its a fuel issue, get a can of starter fluid from the auto store and spray it into the intake and try starting the car. If it fires up momentarily, then you may have something with it being a fuel issue. I'm puzzled. What is the real problem with the car, please?

Yea, I am thinkin that my car won't start from lack of fuel. I mean there isn't much else stopping it. Coils are working, I get a spark. I mean the car is tryin to start & won't. Just seems like one of the few things left. Any other suggestions to what the problem could be? Thanks.

You say it tries to start. I think I read in an earlier post that you did the anti-flooding trick with the ECU fuse. Got spark. Are the wires from the front coil assy going to the lower plugs? The wires from the rear coil assy going to the top plugs? It still sounds flooded to me or extremely weak compression either from the fuel washing the oil away or just being worn out. What might help the compression is to pour a little oil in the lead spark plug holes, turning the engine over for a couple of seconds, reinstalling the plugs , spraying starter fluid in the intake and try starting again. Yet another thing could be a large inlet leak like a vac hose off, clamp on the inlet duct loose or crooked . Large vac leak would keep the thing from starting. Worst case scenario is to push or pull it with another car. By the way did you crack the banjo bolt with the plug jumpered with a wire? Did it spray gasoline?

Ryde _Or_Die

Yea, the front wires are going to the bottom plugs. It does seem like its flooded to me as well. I tried to un-flood it so many times though. It worked the first time I did before. I mean I know I have good plugs(brand new) & the wires are good ones & new, & I get a spark from them. I looked at the fuel rail(or what I can see) & it looks like I have to take apart my engine to get to the banjo bolt. I am having alot of trouble with this. I am goin to look at all the hoses again very carefully. Damn this sucks. Thanks though Hailers, you have helped alot. Keep up the suggestions. I am also gunna try the starter fluid. You take out the filter, right? Spray it in directly? I think that may work. I mean what kills me, is the engine ran fine, like just about perfect except for my shitty exhaust. Hmm...clogged cat couldn't do that could it? I mean make the car shut off? Thanks for any and all replies.

Ok, there is another way to tell if it gets fuel. Low tech. Pull the lower plugs. Stare at the lower holes as someone spins the engine. Do you see a mist of fuel coming out? Need to make sure the battery is charged good before doing this. I'll bet you/ve been charging that battery several times. If you do see a FUEL MIST try the following. Pull that intake duct off the passengers side of the engine. The one held with two chrome nuts. The butterflies are exposed now. By hook or crook pour about a Coke can's worth of motor oil down in the engine. Spin the engine with the lower plugs out , for three or four seconds. Put the intake back on. Put the clean plugs back in. Spray starter fluid in the intake(Yes you can pull the filter out to get a better shot at it). Try to start it. I'm going to continue this on another post since they limit the lines......

CONTINUATION FROM ABOVE....Prior to doing the above consider this. Get a helper. Go to the left hand rear strut tower,the one with the speaker in the top. Now lift the carpet up from the floor of the rear area.To the left of the floor You should see the wire harness going to the fuel pump. Follow the harness where it will run under the carpet covering the strut tower. There is a harness disconnect half way up the tower on the rear side. Pull it apart. Yes its difficult to get your hands on the first time. Have your helper stationed there ready to reconnect the harness at a seconds notice. Now try to start the car as described in the first post i.e. with oil and starter fluid. If by a miracle the car starts, you helper needs to lickity split reconnect the harness. I mean in a heart beat. A nanno second. Sorry I know the pulling the ECU fuse is a way to do this, just not my way. Its inferior. Second rate. There is also a plug under the dash that disables the fuel pump. I just have not got around to finding it. I loathe under the dash work. I'll try to think of other things later.
