this is actually a pretty easy circuit to deal with, and ill first explain to you how it works then tell you what you should look for...

a constant 12v is provided to the asd and fuel pump relay along with the pcm.

the pcm then has a KEY ON power circuit. when you turn the key on, the pcm now activates all KEY ON circuits (fuel pump is one of them). the pcm does this via a ground signal.

so the asd relay has 4 pins. 12v power constant, 12v power feed, ground, and 12v power KEY ON. the relay always has power via battery/fuse box, then gets power via another fuse when the key is turned on, then gets GROUND from PCM when key is turned on, then has a pin to deliver power to associated relay circuits.

once the relay receives a ground signal from the pcm, it triggers the relay and activates SEVERAL sources via a junction connector under the PCM. it sends power to the fuel pump relay, coil, alternator, crank position sensor, oxygen sensors and a few others.

the fuel pump relay in your case is next in line. it has a fused 12v constant source via battery/fuse box. 12v Key ON power via ASD relay (this is a power activated relay, where as the ads is ground activated), a aconstant ground, then a signal or power output pin (which goes to the fuel pump). At this point once the fuel pump relay gets its power signal from the asd relay it powers up the fuel pump for a time delay of only 3 seconds. the fuel pump gets its own ground fyi via another circuit. after 3 seconds you will not be able to check for power at any of teh ASD powered sources UNTIL you begin cranking or the motor is running.

now you know how the system works, grab a power source, and apply direct power to pumps power pin. if the pump primes and runs you have a good pump w no power source.

this time take fuel pump connector in hand, and a dvom, have someone turn the key on for u while you check for power at the connector to the pump. if you have power then the pump isnt ur issue... if you dont have power, move along to the fuel pump relay. check for power at the power pin from asd relay when you have a buddy turn the key on... remember you only have roughly 3 seconds to cheeck for power b4 the time delay which is set into the pcm turns off. and just keep following the circuit back until you find the problem/

i think this is by far the first post to give me a headache lmao, my first suggestion is to get a manual of some sort for that exact car, secondly read carefully what the guys post to your questions, some times the answers are not hidden, well for the most part they are never hidden lol. just because you replaced the dizzy dont mean it cant be bad, as a mechanic i have seen it time and time again new parts being junk. with that said im going to go find an asprin and do some thinking about this and if i come up with somthing new ill post it here

READ FIRST!! I had the exact same issue with mine. My car wouldnt crank and my fuel pump would not prime. I dropped about 500 dollars in it before i figured it out. Even had a mobile mechanic come out and he couldnt figure it out. COIL PACK COIL PACK COIL PACK!!!!!!!!!!!!! It will cost you about 80 dollars at autozone. TRY THAT FIRST!! If you are looking at your engine, it is on the right side at the top. Your spark plug wires run straight to the distributor cap that covers the coil. I also replaced my fuel pump but it might not have been necessary. Try the coil then if the fuel pump wont prime replace the fuel pump. There is an access panel under the rear passenger side seat. Do this and let me know what u get. If it doesnt work i will lead you further.

Welcome to The Forumz Matthew! Do you have the Coupe model also? Drop by the Newbie checkin page and introduce yourself to the whole Forumz Family(especially if you are a Coupe driver) And which motor are you speaking of as the 2.0 and 2.5 are TOTALLY different ignition systems.

I am sorry, but I only read of ONE tag on member posting that his problem was on a 2.0 motor. According to my reading the original posted never came forward with a definite motor size, not even in his info page or thread heading. But alas this had been a long DEAD thread also, going back to 2009.
I do know that my 98 2.5 does not have a separate coil pack mounted anywhere... it is inside the distributor.
Please check in and tell us all just what you have and fill in your profile page with your 'Vengers specifics. Welcome aboard!

EDIT: After searching threads by the original poster... it truly is a 2.5 and his problem was a defective distributor, NOT a coil pack.

I have a 99 changed fuel pump anf filter its not running yet 3 weeks now
This is a VERY OLD thread with many "add on" posters...You need to start your own WITH VEHICLE SPECIFICS of year, engine size, miles and what you have done on it for repairs/maint already.
