You may have fuel pressure but is fuel pressuer high enough. Need to put pressure gauge on and check for proper pressure. If fuel pressure is good then could be bad fuel pressure regulator which I believe is mounted on the fuel injector rail after the shrader vavle.
I had the same thing happen to me, and I spent $250 on a new fuel pump, another $60 for the regulator. The car would start and run for about 1 or 2 seconds and turn off. I read on a website about the Malibu doing this and it was the theft system that was kicking in and shuting down the fuel. What you need to do is turn the key on for about 10 minutes or until the theft light stops blinking; turn the car back off and then back on wait 5 seconds and turn over. I guess that there is an issue with the theft system misfiring and causing it to lock up. I hope that this works for you with out costing you anymore money and headache.
under neth intake manifold replae fuel lines while your under there.
Have it pressure tested, the intake gaskets have probably failed.
I have a 2000 Malibu, I can help you out if you can give me some more info...where on the intake manifold are you referring to?
The '99 has more bolts. If you have the lower intake also, you can swap the whole thing. The upper alone wont fit. Intake issues are very common for these cars.
2010 chevy malibu intake position sensor
3.1--upper intake 18 ft lbs --- intake 10 ft lbs...
on 3.1 v6,it is---intake 10 ft lbs-----upper intake-18 ft lbs,
same place all restrictor plates are, intake manifold, but the Malibu doesnt have one u can remove, it is build into the intake so u would need a perormance upgrade
Ensure fuses are good. Is there injector pulse, fuel pressure, and spark? Has work been done recently? Is there proper valve and ignition timing?
You do not, you have to replace it.
secondary air intake malfunction
Around 30ft lbs.
F.u.b.a.r.ed it ?
The engine needs fuel, compression and spark to run. You are missing one of those, probably spark.
Remove the intake manifold retaining bolts on your 2003 Chevrolet Malibu. The manifold will come off. Remove the manifold gasket and clean the surface. Put the new manifold gasket on and reverse the process.
diferential pressure sensor intake manifold plausibility
Cylinder heads require 33 ft #s & 90 degrees following... Lower intake is 115 inch #s. Mitchell On Demand states 44 lbft & 95 degrees for 1999-2003 Chevy Malibu cylinder head torque specs for V6 3.1L, lower intake manifold 62 inlb then 115 inlb tightening in a circular pattern starting from center.
Low presssure side - larger hose from the compressor
It is in the intake manifold close to the thermostat housing.
It is between $65-$85 for the gaskets.
under top plenum on 3.1 engine at intake manifold.
Check under intake is not a PVC is a air/oil separator
what is the torque specs to a 2002 Chevrolet Malibu 3.1 liter motor. Need head and intake torque specs. and sequence.
Check the fuel pressure regulator.
In a 93 it is under the upper intake. You have to take the upper intake off to get to it
