Oh and that is correct on the engine size. Thanks bnaylor.

If it starts with carb cleaner, it means you have no injector pulse or fuel pressure sufficient to accuate the injectors.

The Egr Valve Is Electronic So Dont Look For A Vaccum Line.if It Was Stuck Open It Might Not Start.cylinder No 6 Is The Closest To The Vave Passage And It Would Lean Out Enough To Set A Misfire Code.try Unplugging The Valve And See If It Will Run.also Try Tapping On The Valve With A Hammer Very Lightly And It May Caome Unstuck.

Is This A 3.8 Or 3.5

[maxwedge]

3.8.

These Engines Have A Problem Where The Upper Intake Melts Where The Egr Stove Pipe Comes Through The Lower Intake.there For Flooding The Engine With Coolant And Causing A No Start Condition.pull The Air Inlet Hose Off And Check It For Signs Of Coolant.also No 6 Cylunder Is The Closest To This Problem.pull The Number 6 Plug And Check It For Coolant.if So You Will Have To Replace The Upper Intake.

If you do find coolant in your cylinders change your oil IMMEDIATELY. dont mess around with it, it could cost you your engine. Go out and buy a couple value jugs of SuperTech and get that oil changed.

If you have oil in your cylinders you also have it in your crankcase most likely, and oil and coolant form a lovely acidic mixture that loves to eat away and those precious engine internals.

good job on the intake manifold 355sb, even though ive experienced myself I hadnt thought of that.

But most of the time the engine wont even turn over with coolant in the cylinders, but its worth a shot anyway.

Gentlemen were are getting way ahead here, the engine cranks, no mention of coolant loss, I think the prior suggestions of checking FP and or carb cleaner starts are in order before we suggest an engine overhaul!

You Wont See Any Coolant Loss Because It Is Comsumed By The Engine

True, but that shouldnt cause a no-start condition, if it fails horribly, then yes you will have a no start condition, but youll also have a no crank condition.

Like was said, check the fuel supply first. See if you can hear the pump kicking on.

I Have Seen A Vehicle Crank But Not Start With This Same Problem

Hi
Sorry for the suggestion that the EGR was vacuum operated - again I have mostly Ford experience. With that said, I looked in my '99 OEM shop manual. In the section on 3.8L engine control, it lists the trouble code descriptions. It lists code 1404 as EGR valve stuck open. For the 3.5L it says 1404 is pintle position. I would focus on the EGR.

Good luck

What are you talking about? The coolant leaks from the cooling system into the engine and is burned thru the cylinders lets say, so the radiator and the coolant jar don't show any loss, it is really getting silly now!

[beabeliever]

when we removed the egr there was coolant on it does that mean anything? Also we were told to pull a plug and crank the engine to see if water (or coolant) would squirt out which would indicate the intake thing but there was no liquid. Just thought I'd share that. I have not yet checked the fuel pressure as I do not have a gauge but will get one and post results when i do.

also, the car has had a coolant leak for quite awhile it seemed to be coming from the upper radiator hose about a month ago the leak seemed to have fixed itself.... does that mean something?
