my truck doesnt run right ... PLEASE HELP

[DollaBill]

ok i got a 95 hardbody , when i got it it was running right , dude said it needed a MAF sensor (truck didnt have one on it when i got it)
i bought one off ebay , not 100% sure its good , but guy was parting his truck out on there , neway i put it on there and still does the same thing , i also cleaned it with maf cleaner

this is what my truck is doin:
at idle it seems to run fine , it will rev up to 1700 rpm with no problem , when you first crank it up ,
once it gets to 1700 rpm it acts like it has a rev limiter , wich to me i thought would be the maf
after it runs for about a hour or so it gets to where it wont hardly run , it wont take the gas atall when you are tryin to take off from a stop , it will still rev up fine in nuetral, it just wont hardly pull itself

the check engine light is on , i have tryed to read the codes twice and ended up clearing the code , so if someone could tell me how im suposed to read em then i will get the codes so we can go from there

and is there neway to check a MAF sensor?


.........THANKS IN ADVANCE

are you running the stock filter on there or some sort of intake?

[DollaBill]

it has a cone style filter on the throttle body , like the filters on a cold air intake ... was on it when i got , truck doesnt have a hood

[1sick94hb]

sounds like a possible failing fuel pump!

[Jokr]

i agree sounds like a fuel delievery problem

[98pacific_frontier]

yeah could be fuel, was the truck like this since you got it?

[JsD21HB]

check the plugs see what they look like and u said that it wont rev higher than 1700? have u checked the fuel pressure? could be an igniter. is the engine bone stock no emmisions removal or ne thing. tps could be out of adjustment or just bad test everything.

[DollaBill]

yes the truck has acted like this since ive owned it

heres pics of what the motor looks like , i didnt remove the stuff off of it so i dont know what all has been removed

how can i check the fuel pressure , i know the fuel pump is jerry rigged , so how could i check the pressure

[DollaBill]

that pic was b4 the maf was installed

[Ice]

prob fuel pump or even a wiring going to the fuel pump..... ive had a wire get cut from the fuel pump.. thing ran fine idle , then when hit the gas it would die or sputter, but then idle fine.. come find out it was a wire that got cut...
so i say wires or even fuel pump...

[DollaBill]

thanks for the help mat ... and everyone else , im gonna go check the fuel pump and wires and ill give an update later

id try putting on the air diverter,lotta people forget that....

[much2fear]

Hopefully it's something simple

[Ronnie]

I would say its your intake. The maf is very sensitive and causes problems when you change the intake from stock. I would try putting on the stock intake.

[JsD21HB]

im leaning toward what ronnie said or just a bad maf. possibly bad wiring, download the fsm from phat20g.com and use the ohm meter, thats the best way to do it man. my car just did that same thing a second ago maf got unpluged and it would rev to 1700-2000 and run pig rich.

[DollaBill]

i put the stock intake on it off of one of my buddys trucks and it still does the same thing , so im goin in the morning to barrow his maf to see if that fixes it ... nemore sugestions

"id try putting on the air diverter,lotta people forget that.... "

what is the air diverter? ^^^

[JsD21HB]

little metal thing that sits over the 2 studs on the throttle body. it diverts air around and into the maf supposedly.

[98pacific_frontier]

yup without that truck runs like shit,jerks,stalls, and even if your maf sensor is working properly the air isnt getting directed there.try it out let us know.

[DollaBill]

ok ive put the intake , and that little metal thing , and a maf off my buddys truck , and it still dos the same thing

im sur i was pretty hard on the motor , but i reved it to 1700 when it starts cuttin in and out , and then sprayed it with starting fluid , and it reved up like it should of , so now im thinkin its deff goin to be something to do with the fuel

is there a way i can check the fuel pump to see if its pumping enuff presure , and where is the fuel filter suposed to be , i have looked from the tank to the fuel rail and cant find it , i think some one has taken it off and nevr put one back on

[SmashinHaters]

filter shouldnt be far from th firewall on pass side, follow fuel line, i coulndt tell from your pic if it was missing.

[DollaBill]

yea i found where it was suposd to go , some one put a lil piece of rubber line in its place
