the lights and electricity are working but the fuel pump doesnt seem to be turning on. Depressured the fuel when i was working on the manifold but reconnected it... Just wondering if it makes a difference if i connected the negative first and then fuel pump wires? But yea i have no idea what is wrong. PLease help asap ><

what year is it?

When you removed the intake manifold, did you take off the top one or all of it completly off?

can anyone help? i think its an electrical problem but i have no idea where i couldve messed with the lines.

well uhhh

Did you check your EGI fuse? you could have shorted the fuel pump connector while working with the battery connected. I just re-read
and the fact that it has no fuel or spark all of the sudden makes me think you blew the main fuse. Check all under hood fuses.

even the main fuse is good? maybe a starter issue then?

when i took of my head i forgot the discounect the battery and so i blew my main fuse and replaced it and now im good

i had others suggest that i might not have plugged in the MAF sensor but its there..umm starter is fine so im completely lost

well uhhh

it will start with no AFM, the ecu uses a start up map that doesn't read the AFM for about 30 seconds or so until it switches to reading AFM.

just making sure if the ground is correct....umm the ground cable that goes off the negative battery connects to the long bolt on the starter right?

are all the throttle position sensors, leading and trailing coil, all the good stuff currently plugged in? and you can always re-do your grounds to double check

the thing is like ive never touched any electric parts other than those on the starter and tranny, and also the manifold. However i've already connected all connections that i disconnected so what i dont understand is why these things arent working....

No fuel and no spark equal a ENGINE fuse being blown. It's in the interior fuse box. Swap the one there with another.

ENGINE fuse pulls in the MAIN RELAY and supplys power to the circuit opening relay and fuel pump. No MAIN RELAY being pulled in means no power to the ECU. ECU produces Spark.

ENGINE fuse is bad.

engine fuse is good
old owner's alarm wiring is bad

So i guess something triggered the alarms ignition switch to go off...but now its fixed! yay the end thanks for all your guy's help and im glad its fixed and i can drive it now!
