2008 Jeep Grand Cherokee 3.0 Mercedes CRD will not start


does it start and run for 3 seconds on test fuel

yes, engine ok, EFI bad.

no, bad engine, engine must be good to run.

EFI cant run bad engines..

so compression at spec......????



why beat the EFI to death,

all engines run on test fuel.

with gas engines, takes spark and good engine

on diesel, takes only good engine. simple huh (and some air)



for test fuel try diesel in a spray bottle into the injection port.

google this

or use youtube on test fuel on any diesel car. or truck



this is called basics....... basic basics.

1: good engine, and pumps air ok. (must breath)

2: good fuel.

3: test fuel works now. if not check above.

2003 ford Taurus been sitting up try to start just spins over want start


Crank but no start is either no spark or no fuel to engine.
Best way to narrow it down is to just spray a 1 second dose of starting fluid into the air intake before you try to start it. If it does start then die it is lack of fuel or bad fuel to engine. In all the modern EFI cars the most likely faults on fuel failure with fuel in car are:
1. fuel pump failure.
2. fuel pump relay
3. fuel filter plug

If it fails to fire on the starting fluid it is lack of spark, and the trouble shooting procedure will be to investigate the coil pack.

My 1988 t-bird will not start. electric fuel pump is working and has spark. it is a 5.0 EFI.fuel comes from the bleeder valve as I try to start it but will not start. can spray starter fluid into intake...


Does the fuel spray out of bleeder or run out. Should spray out with a lot of pressure. Have you checked fuel filter? If its not spraying out good and not the filter i would replace the pump.

On a hot day my car won't start.some one told me it was my distributer.could that make my car not start?


Depends on what you mean by "no start". Is it that it will crank over and not fire or will not do anything? Will it happen after driving from a cold condition(meaning, first start of the day it will fire but after driving it has issues)? How is your maintenance and what has been done recently? Please let me know.

'94 S 10 Blazer V6 Vortec EFI. Fuel pressure good, new fuel injectors installed, fuel pump works ok. Only starts with starter fluid sprayed into air intake. Any Suggestions?


your statement is fuel pump work ok, have you tested for proper fuel pressure. just because the fuel pump works it could have less pressure needed to start the engine. maybe the fuel filter is plugged. start out by replacing the fuel filter, if this doesn't fix it, you need to pressure test the pump. even 10 psi reduction in pressure will allow the engine not to start.

2000 Toyota RAV4 has spark but will not start. Tried spraying starting fluid down air intake but it won't even give me so much as a putter. It doesn't have any alarms or security features.


Check your fuel pump.

The pump should make a sound when you turn ignition switch to the ON position. If not check "IGN" fuse and then "EFI" fuse located in the engine compartment fuse center.

Then also check the "EFI main relay"

Finally check the "circuit opening relay" which is activated if the vehicle is in a crash to shut off the fuel.

Car simply will not start or fire


Assuming it's fuel injected,check your fuses (there is a fuse for the EFI and fuel pump). If the fuse is fine, then the issue is most likely your fuel pump (located in the fuel tank). You can change the fuel regulator (located under the air cleaner unit) but it sounds like a bad fuel pump.
If it's not fuel injected, please post back for other options.
