Jay your rambling now. Kirk said he could not smell fuel. Damn you might owe Ryan that Beer

im from Leeds, up north.

All he did was take the plug boot off, you won't smell fuel like that. Pull the plug to see.

Oh oopsi read it as he did smell gas when he did that. what ever I still hold my ground.

Second thought... dont go buy that sensor... its 100 bucks a Mitsubishi!

Under $30. for an aftermarket one, and OEM should be under $65. You must be shopping in the wrong places

Ok I hate you guys!

After driving around all day, It dosent start this morning.
!

Went to remove the connector from the cts... it brock! May be the problem but I fixed it wit a 2g pigtail and sensor.

Still no start........
Checked plugs.. dry..

Took return hose off fuel rail, then attatched a hose to a bucket. Cranked it over. Nothing!

So I jumped the fuel pump test connector and got dribbles. Is that normal? I expected more.

What does your FUEL Gauge say? You should get full pressure if the pump is running.

What are the temperatures like there? How about some gas line antifreeze?

Says im got a 1/4 tank.. I listened and after canking it.. I dont hear he relay shut off. So later im gonna swap out the mpi relay since i have about ten of em.

Ziggy It was -27 this morning when she tried tostart it.
.

shot in the dark.. but could one use the a/c temp sensor in the thermostate housing for the ecu? just swap the pigtail wires? my ac dont work anyway.

Is it the same resistance?

If you aren't getting fuel while the pump is running, I suspect a (frozen) blockage...

No the A/C switch is just a switch on/off at a certain temp.

ok maybe thats my problem.. I used a coolant sensor with a white plastic area. It prolly is the ac sensor. The sensor I put in yesterday fell apart when I tried to fix the pigtail.

Eitherway Kirk.. I hope yer reading all this as you should be doing this aswell.

Just waiting for the weather to warm up.

Ya me too .. its gonna be plus 3 next week. Part source sells the proper sensor for 40.

Yeah it is too flipping cold right now. I got stuck outside on 2 no starts today. Only my left hand has defrosted so far.

So does that mean I get a beer?

My car is always garaged park and I usually don't leave her alone for too long if it's outside. Cold is just a mind set, I was just outside it's not that bad!

Ryan .. not yet lol. We havent ruled out the sensor in Kirks car. And mine could be the sensor as I replaced it with a AC sensor.


Byan . I would have her parked in the garage but theres a 2g in there.

Jay I thought you didnt have fuel. Sensor wont do that.

As for cold being a mindset thats silly talk.

Ok frack you guys and your...

Anyway.. I found another 1g cts and swapped it back in. and after a bit of rough cranks it fired right up. Guess tring to use a a/c temp switch will confuse yer ec so bad.. it wont send any fuel. Plus while it was running it still dribbled out the hose i had on the fuel rail return after the regulator.

Unless Kirk has anymore input to provide to this thread, I think we're on hold until we hear from him.

So i had a look tonight and im not sure what to make of it, i cranked it a fee times pulled the plug and it seemed dry there was a faint whiff of fuel but not what i should be smelling, and i couldnt see spark either, i plugged a spark plug in to one of the leads and sat it on the manifold, even if the battery is going there should be a faint spark right?

As long as metal of the plug was grounded you should get spark. You could use a jumper wire to ground it or get a buddy to hold it tight to metal he may get a slight shock but it wont really hurt him

Just a thought guys, in my earlier posts i explained how i couldnt hear my fuel pump when i turned the key, and was promptly told i shouldnt hear it, what else could i have been been hearing? Or more to the point what should i be hearing because it is too quiet im sure i used to hear something.

You should here your MPI relay click (Behind the Radio) then as you crank it should click again to turn on the pump.and a few other relays underhood will cycle aswell.

Do you get a check engine light on when you have the key in the on position???

Yeah see i can't recall hearing that I'll check,for the cel later.
Thanks for the help guys and if my posts are a bit jumbled and messy, im sleep deprive(baby) and with it been so coldd im trying to 10min diagnose lol.

So kirk.. hows it going? I may have to suggest diognosing the sensor first. ONLY cause the sensor is real expensive. I had a couple laying around plus I have a yoor wreckers near me that I can get them cheap. Swapping them is easier for me.

You may wanna try some fuel line antifreeze aswell.

Ok so i have no check engine light when i turn the key, gotta be ecu right?

does it start? what have you done to it? Now that its warmer.. Take a 12v jumper to the fuel pump test connector to see if your pump works. If it does then crank the motor over with the key. If it dosent start listen for the click under your dash. if it dosent click then its the mpi relay. if it does click then it may be frozen fuel lines. But I would def check the cts cause if it dosent start today.. then that might be your problem.

Unless a mouse chewed your wires. It does happen.

Could be mpi relay or ecm. How are your multimeter skills?

Time is my problem at the moment, as of Monday i have a car to steal parts from, what should i start with? There is no clicking with the turn of the key btw.

The chances of it being the MPI relay are slim.

If you have no CEL, it could be due to the following:

MPI FUSE
Burnt out CEL bulb
Failed ECU
Failed MPI Relay

Check them in that order.

Hurry up and fix it so Jay can prove to the mechanics if he's right or not, it's very important to him.

Im just trying to help.. with an idea that helped me. you guys challenged my theory..

Now that you have a parts car.. if you got the cts.. swap it. Dont bother taking yours out.. just take the parts car sensor and plug it into your cars harness and start the car. Try the fuel pump test conector and listen for the pump to come on..let us know if you hear it hum.. Then swap the mpi relay. Then maybe swap ecus if you can.

You can try swapping ECMs or MPIs. Althought Jays theory on a ECT is valid for an engine not starting or long cranking. It doesn't make sense for no CEL or fuel. Most probably the ECM caps have leaked and damaged the board....you should still test it.

Will toy these asap thanks for all the help it will take a while but ill get all these tested as soon as i can.

Right I grabbed the ecu and the black relay sitting behind the radio, will swap them out tomorrow hopefully that will fix if not rule out them as problems.

It was the ECU, plugged the other one and she fired on the first turn, thanks for all your help guys couldn't have done it without yas!!!

Glad you got her fixed.
