wassup guys,
i have a 2003 EVO8 with 45k on it. mods are intake, turboback, gsc s1 cams, walbro pump, intercooler, full i/c piping kit, and random other bolt on stuff. Was tuned by Matt from SWIFT Motorsports and put down 307whp and 280wtq.

Two days ago i went to start the car and when the ignition went to "start", i got a loud whine from the fuel pump and it wouldnt start. left it alone for a few minutes and tried 2 more times and it started. went to work and did a bunch of running around all day and not another problem. it started each time. The next morning,(Yesterday), same thing. only this time it wont start, no matter how long i wait or turn the key. just the loud whine from the fuel pump.

Assuming it was the pump, I swapped it out with the stock pump today. Now the car will turnover but it isnt starting. the plugs are iridium BPR7EIX and they were put in in March/April time frame. Ive never had this problem before nor any other problem with the car. No CEL. Has anyone else had this issue or know what else i can look for? I searched but couldnt find anything. Thanks

sure that the stock pump did not get stuck over the time ???

 

battery? wat kind of batter do u have? also might need a new starter. just a guess. tho could check the battery and swaping out another one to see if that is the problem bc that happen to me before.

 

have you checked your battery? How old is the battery? Take it out and have it checked by Autozone. Or check the terminal connections.

 

i checked the battery. all those times trying to start it was bringing it down. so i put some cables on it will my wifes truck was running just to be sure there was enough power. still the same thing. its an "Interstate" battery. about 1.5 years old.
the rear seat is still out. i was listening for the stock pump and its doing what its supposed to when the ignition is on and when i try to start. the walbro was only in there for a year!!

any other suggestions? all is appreciated.

 

crank sensor, and maybe ignition issue ...

 

are you getting fuel,and spark?
did you just install anything recently?

 

Yes! thats the same thing I was about to ask. Check for fuel and spark.

 

just went outside and did another check. fuel i'd say yes. spark not sure. i popped all plugs out to make sure none were fouled. put em back in, still same thing. turns over but wont start. i havent installed anything recently. last mod was my cams and that was about 4 months ago. i only know to check spark by pulling a plug wire and looking for the spark with short cranks. but i have no one to do the short cranks for me. any other way to check it when you're by yourself?

 

Did you ck the coil pack fuse?

 

That was going to be my first guess was to check and see that your plugs weren't fouled. Does the cranking of the engine sound clean when it cranks over, or does the car crank kind of sluggishly or in a weird manner?

 

check the fuse.

 

where's the fuse at? update, the car is at the dealer right now. no fuel. i guess what i saw was some excess in the lines. while i was hanging out with my car at the back of the dealer, the tech changed all 3 relays and still nothing. one on the firewall and 2 behind the steering column. still no joy. hopefully they will find it by tomorrow and it will be something small and cheap. this dealer is the best when it comes to service, especially on modded evo's and sti's.

the car cranks perfectly fine as always. all the cranking ran the battery down a bit but that was all.

where's the coil pack fuse. my fuse box under the hood is all in Japanese. tried to make out symbols and stuff.

any other suggestions? because when i go back to the dealer to help them troubleshoot, i want some fresh idea's. thanks for all the input guys. i love my evo family

 

at th dealer, a crank sensor code was there but they said it was probably from all the cranking and not starting. if it was the ignition, wouldnt it not turn over?

 

Could be the sending unit in the tank, or the fuel pump itself.

40amp fuse under the hood. I believe it is the only 40 amp, and there is a 10 or 20 under the dash you could check.

Maybe the CAS sensor is bad.
