Torque,
I'm a new user and cant' use Email yet and i may not be going about this the right way.
I'm posting this here because you moderate this forum.
you mentioned working on a Trooper in another thread so I'm hoping you can help me. I need to replace the fuel pump on an
87 trooper and i'm not looking forward to it. I've had the head off before, when a broken heater hose resulted in a cooked head. So i know how hard the pump is gonna be to get at.

You ever replaced one before? I'm wondering things like if taking the fender off would make it easier. Any tips? tricks? special tools that would help?

That was an awesome car

At $500 for the Trooper, with a rebuilt motor in it, i couldn't resist

 

My 90 had an electric pump (EFI). I am going to assume here you are talking about the mechanical pump location on the side of the head under the intake assy?

I junked my 90 last summer after the head or pistons went out again. I didn't want to mess with the POS anymore. The engine used 1 qt of oil every 5-700 miles every since it was new. Bad or mis-installed rings in #4 and the dealer would not fix it. I had already replaced the head twice. The drive train was good but the engines and management systems were poor.

 

Torque, thanks for the response

yep, that's it. That's where it's at.
I've had the replacement pump sitting around here for a while now. Didn't think of it till just now. It'd probably be easier,less work and trouble to do an add-on elec fuel pump under the hood. My 83 ranger has one. maybe the dealer will tke the mechanical one back.

The old pump still pumps fuel, but it's been dripping oil out what i'm guessing is the vent. had the bright idea of plugging it and the pump locked up.

Now it's dripping more and it smells like gas. Which leads to to another thought. If it's mixing gas and oil coming out, it could be doing that internally, in the crankcase and that would explain the drop in oil pressure to O at idle.

Never really did want this vehicle, shoulda sold it as soon as i got for a small profit.

 

Didn't the Trooper use a GM 2.8L engine back then?

 

The electric pump is a good idea. You need to get that mech pump off there b4 it fails completely and does damage asd you will also need to block off the mounting surface with a plate. With all of that work involved it may be just as easy to replace the pump. My manual says it may be necessary to remove the intake to pull the fuel pump (nice design). The intake was SOOO much fun on the EFI version.


No, this one is a 2.6L inline 4 and the other on later models were 2.?L V-6 with zero torque. Could have been Cheby but I don't know. The 4 was the better engine for off road. I lost track of what they used after ~92. AFAIK the 2.6L-4 was a Isuzu engine. The gasket set matched some Honda engine also. I think 90 was the first year for the V-6 but they were gutless so I got the 4. I thought they might have been 2.6L that year but I don't remember, -slept too many times since then. Izoozoo is not my thing.

 

yep, that's why it's good to talk things around. didn't get that far in my thinking .........hole would have to be covered. if i can cover the hole, i could get the new pump on.

i was just looking for some one who knew more than the manual. a short cut, ya know?
Well, thanks , had to try.

 

To get the EFI manifold off you had to remove the PS pump and bend the battery box hold down out of the way as well as remove all of that junk on the fender. The cooling system hoses are also routed very stupidly. Have fun with the carb version tho...
