    Recheck your work, you most likely left something unplugged, recheck all the connectors, is it no spark?

A COMMON PROBLEM I'VE SEEN MANY TIMES IS THE CRANK SENSOR DISRUPTING COMMUNICATION WITH PCM. UNPLUG THE CRANK SENSOR AND CHECK FOR RESPONSE OF PCM. IF COMMUNICATION IS NOW POSSIBLE YOU HAVE A BAD CRANK SENSOR. IT'S A PROBLEM I'VE SEEN NUMEROUS TIMES. DOUBLE CHECK YOUR TIMING.

07 suzuki reno vin #kl5jd66z37k643089 replaced the head gasket put together now it will not start no fuel press. or ignition spark


in usa this engine is L34 or U20SED
i guess you are working with no scan tool????
that be super hard, to out guess the EFI system.
we cant see electrons so.. tools make the man.
DOHC engine
if there is no spark times 4, did you check all 4?
After all 1 cylinder or all 4 can fail. telling the
mechanic big clues
if sparks ok test fuel works (sprayed).
is the timing belt under 60,000 miles new?
if the belt slips compression x4 drops radically.

head off, well i think this is an interference engine.
its DOHC, so if you bent the valves by driving until the belt slipped, oops, you killled the head.

funny thing is no history here
am I to guess, engine died? and the head was removed
was the head tested, when off?
new head, rebuilt head,
check for warp
and do the valve test with I use kerosene
in the combustion chamber to see if the valves are not bent, if bent the fluid leaks to the ports.
oldest test on earth this, 100 years. old.
and more, take it to a machine shop (head)
and get it pressure tested, etc>> now that be savvy.

My 1998 Jeep grand Cherokee can crank but will not start


If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If you have spark everywhere, check fuel pressure and fuel injector pulse.
Can you check for applicable trouble codes?

Hello Sir:

There are 2 Problems that can prevent your car from starting:

#1) Make Sure your getting Fuel

#2) And Check to see if you are getting Spark to your Spark Plugs,By pulling off 1-Spark Plug wire and take plug out also, Put spark plug back in the Wire. Have someone crank the engine over,and see if theres Spark at the Spark Plug.

#3) If your car is'nt even cranking over,then the problem is in either your Ignition switch,starter relay,starter,or it can be as simple as a relay or Fuse, check in your fuse box inside,to make sure ALL fuses are good.

#4) Then under your hood you should see a plastic Cover Fuse and Relay Block as well, Check these also,Mainly if its labeled Crank,or starter. Also check your Starter relay. they are a Larger componet in the box under your hood.

#5) to check this relay you'll need a OHM meter to check for resistance. also check the EMC Fuses or Relays.

#6) if no fuel check fuel pump fuse and replace fuel filter 1st.

#7) If no Spark make check your Coils.I'm sure if you follow these tests you'll locate your problem.

Car turns over but does not start. Battery good


If it over heated, could have bad head gasket's, fill radiator with water, crank engine with radiator cap off, if water is push out of radiator while cranking, bad head gaskets', also remove spark plug's, crank engine if any water, bad head gasket, also when spark plug's removed, check for any water on them.If there is any water on plug's, bad head gasket, also could try doing a cylinder compression test, if bad compression, head gasket, no compression, wont start that way.

'96 Dodge Dakota will crank, but won't run.


a bad crank sensor or dist pickup plate can cause this.... check the fuses in the fuse block under the hood for any blown ..... a bad auto shut down relay may cause it .....try putting a test light on the green and orange wire and see if it lights up when you try to crank it
