ok i have had my main relay out for a few weeks and after some great help on here (thanks guys) i got that straightened out. last night i turned on my car and the fuel pump primed i turned the key but it cranked slow and hard (dead battery)

so i got a friend to push me down a hill to bump it and it wouldnt go. now when i turn on my car the pump doesnt prime and my car will not start. (will be trying starter fluid in it tomorrow to see if it will start up or not)

i have already made sure my grounds are good. unless there is a ground in the back that the pump goes to

 

Sounds like a bad fuel pump. Same thing happened to me,make sure your main relay is good.

 

ya i will be making sure i is tomorrow by putting in one out of a car that i know works fine. also how notice able will it be to go to a fuel pump out of a 91 sedan lx from a walbro not sure on the size i was just told the fuel pump was larger and a walbro when i baught the car. my car only has mild bolt ons and slightly bigger injectors.

i would rather use the fuel pump from my parts car but if it will be a huge difference then i will buy a new one

 

dpfi or mpfi?

With the key in ON(II), does the main relay plug get voltage on the Yel/Wht and Blk/Yel wire terminals?

 

mpfi on obd-1 and im not sure i have not checked that. but my relay dousnt buzz and i just resoldered all the joints. i have a friend with a meter that i could use but i need to wait for his room mate to get back so i can get it from his room. i will check that when i get the meter.

 

The voltage at the 2 main relay plug terminals should within 1 volt of the voltage reading across the two battery posts.

 

ok i checked it and it was like .5 away. also my fuel pump was priming again. not sure why. but my car is cranking very hard like the battery is dead. and the battery was 12.3 so it isnt dead. could this mean starter is going bad?

 

12.3 V is a low battery - charge it.

 

alright i will get a jump later tonight probably around 6 and see what happends. and i thought the battery should be around 12.5 does the .2 really do that much?

 

You really need to have the battery load tested. Most parts stores can do it for free. They will charge it first, then load test it (simulating engine cranking load), and determine if your battery is up to par.

 

Long story short: yes.

 

ok i got my car jumped and the cables were on for like 5 minutes and i tried. it sounded like it cranked strange. like it would go normall for a few turns then slow down for one or 2 then speed up again and repeat. i looked in the bay at my starter and the post on it the the cable from the battery goes to was very loose and would spin around and wobble pretty bad. i tightened the post on the starter thinking that this could be the problem but it still doesnt crank right. i will be putting another starter in to see it this is the problem. i will also try to get a ride to a parts store to test the battery

 

Did you check the transmission ground?

 

yup i i even sanded i a few days ago when i was looking to see what was wrong with my main relay. i will check again though.
