Three months it's been in the shop.
Fuel inj. 4 cyl - runs great otherwise.
problem only in the morning.
Fires on all plugs and fuel is spraying from the injector. It just
cranks but never catches.
When it finally does start up it acts as though (and smells like) it's
So far have replaced:
Oxygen. sensor, Temp sensor, Fuel pressure Regulator, and Mat
sensor. Also tried new
computer - so far no fix.
Happen 3 - 4 mornings a week.
Need help please.
I would assume that this is the Iron Puke 4 cylinder with throttle body
Go back to basics:
That engine never ran smooth, IIRC. I remember putting a new injector
cartridge in mine, hoping it would help. (Not so! Still was a turd)
Mine had a distributor in it. Does yours? If so, be sure it does not have
an internal carbon track, and that your ignition wires, rotor, cap, etc are
in great shape. Any screwup in the ignition and it might not fire
when cold and damp.)
Check to be sure your ignition is putting out a hot spark WHEN it is
supposed to be there. In other words, be sure your ignition and valve
timing is in good shape.
A compression check is a nice way to start the day.
Now, that engine was very very prone to block cracking, (If I have the
It usually cracked at the water jacket inside the lifter gallery. It is
easy to check this if you can remove the inspection plate and take a visual
inspection. The crack will be parallel to the lifter gallery floor, and
1-1.5 inches up on the wall. If you see a whitish line across the jacket
then you are probably cracked.
If you are cracked, then this may be a reason it happens primarily in the
morning (after cooling, fluid transfer, etc)
Remember that the basics say:
(1) you need fuel at the right mixture with air
(2) you need ignition at the right time and high enough voltage
(3) you need compression, at the right time, etc.
If you get those three basic down right, you are likely to start and run
have you bothered to check fuel pressure. Hard starting in a.m. tells
me that fuel probably has returned to the gas tank due to a bad
checkball in fuel pump, and if pump is bad car will crank forever till
it gets system full of fuel. I recommend hooking gauge to fuel line to
check for proper fuel pressure. Turn key on, pump will run for 2 secs.,
then see what you have for fuel pressure. If it's a 2.5 ltr should have
9-12 lbs of pressure. If not, make sure pump runs for 2 secs, if it
does then replace fuel pump.
LOTS of fuel sprays out - In fact I think too much as then when it
does start, it smells and
feels flooded. Another thing I've noted .... used to get 260 - 280
miles to a tankfull of gas
down to 180 miles to the tankful now. Using up alot of gasoline
