ok so i recently had the misfires and changed the plugs and it ran better and its been raining here the past few days so i go and crank the car today about 3 times making little trips then i go to a friends and let it sit for mabye not even an hour go out to leave and it wont start right before i got over to my friends i heard a bad squeaking from the belt area.

im pretty sure my opti has finally pooped on me

so do these seem like symptoms of a bad opti?

it will turn over so i know its not the starter and when u give it a little bit of gas while trying to crank it it will try and start but just wont :/

any help would be apreciated

 

Is the ses light on?

 

yes bc i have no cats and the rear 02's are plugged but havent tuned them out yet so thats why its been on as far as i know

 

It would still be a good idea to scan for codes. Might be a new one or two.

 

well its broke down at my friends right now so ill try and get it scanned as soon as i can then tell u guys what codes it throws

 

Get it scanned for codes first.

If it doesn't throw the exact code for the optical sensor failing, I would say plug wires or you put the wrong plug wire on the wrong plug.

I have a PhD in Optispark.

 

haha nice!

My dad sprayed some wd40 in the throttle body and i can get it to crank but it wont stay cranked unless i give it some gas..so it just dies.

but yea im tryin to get a scanner so i can scan for codes

 

haha

When you crank it can you hear the fuel pump wizzing?
Sounds like ehhhhh from the back seat area.

Next step is hooking up a fuel pressure gauge to the shrader valve on the back of the fuel injector rail to make sure the fuel pump isn't shot.

If there's a ton of miles on the car, you may get really lucky with a clogged fuel filter that needs to be replaced.

My fuel pump died and it did an intermittent slow burn where it would crank and run okay for a little bit and go for a couple of days or so and you're all "it's going to be okay man" and then it died a horrible cold death.

 

Do u mean when i crank the car up or when i turn the key to the on position?

 

Right before it cranks you can hear the fuel pump go ehhh from the back of the car. Sounds kind of like a window wiper washer motor running-

Make sure you get the codes read first, so you don't chase your tail.

I re-read your first post where you said you changed the wires. Check those again and check the opti to coil wire if you changed it.

Look for obvious stuff first.

 

i changed my spark plugs but not my wires yet

ill scan it for codes 1st before i do anything then tell u wat i get

thanx for the help

 

ok i finally bought a scanner and scanned it tonight

heres the codes i got...

P0102
P0117
P0134
P0140
P0160
P0300
P0400
P0441

im about to check shoebox's sight for the codes

I also noticed one of the hoses leading down by the opti is leaking coolant bc my fluid is slowly draining out of my radiator

any help guys?

 

P0102-Mass Air Flow (MAF) sensor circuit low frequency

P0117-Engine Coolant Temperature (ECT) sensor circuit low voltage

P0134-Heated Oxygen Sensor (HO2S) insufficient signal activity Bank 1 Sensor 1

P0140-Heated Oxygen Sensor (HO2S) insufficient signal activity Bank 1 Sensor 2

P0160-Heated Oxygen Sensor (HO2S) insufficient signal activity Bank 2 Sensor 2

P0300-Engine misfire detected

P0400-Exhaust Gas Recirculation (EGR) system

P0441-Evaporative Emissions (EVAP) system no flow (during purge)


the 2 biggest things i see is the EGR and EVAP

 

Anybody have any idea?

it starts when i give it gas but then just dies if u dont rev it

 

When you put the cold air intake on, did you get all of the electrical plugs/connectors back together?
