ya with age they can become faulty

when ya change it be careful not to break it off in the hole.....a common problem if ya force it to much on removal of the old one.

Got it...and thanks for the advice!

If you want good advise then give us the fuel pressure you tested at.

The fuel pressure was 47 psi at the valve.

I dont mean to sound retarded but where in the hell is crank position sensor located at???  I cant find it on this POS.

crawl under from the front of the car and on the back of the engine, about straight down from the 2nd spark plug in the back.  I basiclly just had to feel around till i got it.  It has one bolt if i remember correctly and the plastic on the back is kind of oblong or oval shape with one side a little smaller than the other.

OK...changed the CPS and still a no go.  Now I'm not even getting a spuddering from it.  It still cranks but it still wont start  :icon_sad:

Are we at plan G or H???

Damn........

Coils or Ignition Control Module?

running out of ideas here

I've been battling the horrible performance my TGP has had and I think I've narrowed it down to clogged or bad injectors.  But today (after letting the car sit for four days) it just cranky cranky and no start.  I have spark and the fuel pump is good so I have eliminated the obvious.  I'm just wondering if the injectors can cause the no start thing now???  I have changed the O2 and the MAP and it already has Jeff's chip and x-over as well and two weeks ago I gave it a complete tune up so any ideas????

cat clogged?

You arent allowed to run out of ideas yet... ;) 

The coils are new as of a week ago and the cat I had tested earlier this week and it's good.  I havent checked the IC yet so I'll do that this afternoon but I still dont know why it started and all of a sudden nothing at all.

are you 100% sure the plug wires are routed correctly?  front bank is 2-4-6, rear bank is 1-3-5 (from passenger side to driver's side).  some people get it backwards because of the way the numbers are cast into the lower intake manifold.

otherwise...it might be a long shot but have you checked the timing chain?  i have had one break....pull the oil fill cap and look down and make sure the valvetrain is moving while someone else cranks it over.  hopefully it's not that because if it was you'd likely have some bent valves.

good luck!

Double checked just to be sure like you said and they are correctly routed.  Also I checked the timing and its true on and good to go as well.

I did notice a strong smell of gas when I was trying to start it up tonight and found that it's leaking gas between the FPR and the fuel rail.  Further investigation showed two o-rings with tiny tears in them so I'll be changing those in the morning as no place is open here in KC, MO this time of night to get good o-rings.  I'm hoping it was just not getting enough gas because of the rather HUGE leak there and that's why it wont even sputter after changing the CPS??  That would also explain the gas smell after driving it when it did start last week.

I'll keep ya posted and keep the ideas coming.  I've been working on this so long I'm starting to see it in my sleep   :icon_eek:

Have you pulled the plugs to see if they are soaked with gas??

You may have a FPR that is bad and FLOODING the engine!

That is the only problem with these cars..to many components to fail! ;) :icon_cool:

Best part is when you replace most of the sensors you will have a near perfect running motor and be able to enjoy it to it's fullest! :icon_cool:

I've had it for the night (my hands hurt so bad I can hardly scratch my nuts  :laugh: ) but I will surely look there in the morning after I get a new FPR as I just dont feel like changing an o-ring and not the whole component (just doesnt seem quite right for some reason).

As for replacing all the sensors I didnt really think about it until you just that  :icon_eek:  I think when it's all said and done I will almost replaced every sensor in the engine!  The only thing left to do is change the LCD in the HUD that has burned causing it not to work and cleaning the engine up making it all pretty and shiney and what-not. 

Hell I might be affraid to drive it after all this  :icon_mrgreen: .  NOT!!!!!!!!

r ya sure its not just the slider switch? the one on mine appeared to be fine but thats all it was. for the HUD. thats funny the FPR has issues, thats about the only thing I haven't replaced, got new injecters countless fuel pumps. Its good to replace all the sensors, as they can live a hard life if the charging system hasnt been properly maintained. I believe they would last way longer given clean power, we already have the technology to control giant temperature swings in the engine bay, and advancements in wire connections like adhesive heat shrink added to oxygen free cables help keep out contaminents like never before.

Update ---  It finally is a go!   :icon_lol: :icon_lol: :icon_lol:

After changing EVERYTHING on the engine and checking the plugs and on and on and on I decided to change the coils.  Got the third one installed, drank another beer and said what the hell.  Got in and turned the key and BAM!  LIFE!!!  Sputtered from all the gas and cleaners I loaded it with, smoked for about a minute and then just smoothed right out.  She's purring like a fat cat on catnip!

I think in the process of changing all the sensors and injectors and everything else I must have killed the last coil or something.

Thanks for all the help and advise!  I have learned an awful lot about this engine and cant wait to tweak it up!
