91 stealth es fuel or electrical

[crazylazy9]

My 91 es DOHC 153000 miles is having some issues with the fuel pump or relay or something.

New plugs, wires, dis cap, rotor button, iso servo.

The car had set for six years due to not knowing iso was bad. Got it back running and it ran good for a week or two.

Now it's stumbling on acceleration, fine when idling. It kinda only starts around 2000rpms it cuts back, studdders then eventually will not go like, feels like when your running out of gas. I pulled over the other day when it was doing this and put it in neutral. Opened hatch and the fuel pump feels like it cuts on then cuts off. Leading me to think lack of fuel or relay In park you can rev it all you want and it will run fine. If you stomp on it it just bogs down.
Looked for relay under hood not there. The one near the radio on passenger side is there and clicks on when started and clicks again when turned off.

It's at the point now that you cant go up the road without it cutting back and stumbling took me a hour to get home other day driving 20mph.

Dont know to start with filter, pump, MAF, fuel pressure regulator, drain tank and clean it out etc or is there something electrical making the fuel pump act up like it does....

Any help would be greatly appreciated.

Did you run the old gas that was sitting in the tank for those 6 years of sitting?

Filter. Cheap, easy and should be done anyway. If it isn't the issue you're only a few bucks.

I second the filter needs to be changed common for cars that sit .

[crazylazy9]

Did run the old gas out of stupidity of excitement of car finally running.
I will get a filter in the morning and see how that does.

Do I need to drain the tank or put any additive into it.

Thanks for the answers!

I'd drain it. It's probably halfway to being turpentine after 6 years.

[STLVR4]

Yes definitly drain it. If your lucky your problems were just stemming from bad gas but theres a good chance you fouled your injectors pretty badly. You could try a couple of bottles of fuel injector cleaner and hope like hell it can work miracles.

Good luck.

Today's lesson learned and brought to by the letter M and the 1. :)

That was me as well, I have never heard of a 6G72 DOHC motor using a distributor ingnition.

looked like a dis cap to me lol maybe it's called something else. But I replaced it.

If it's in the same spot in the chain [the 'other end' of the spark plug wires], those are the coil packs.

I'm with the others...drain the tank, change the filter, doublecheck the sensors and vacuum lines to make sure they're connected.

I don't know if it'll be helpful or not, but I've heard that premium gas has more detergents than the cheap stuff; a full tank of that + fuel system cleaner might help. If not [and you can keep the sucker running while it works its magic], giving it a SeaFoam treatment might not hurt either.

Just in case you don't know, draining the tank is easy also. there is a drain plug on the back right side of the bottom of the tank.

I bet some nasty shit comes out of that tank after six years. Especially if it was any percent ethanol.
