tims auto repair :

tims auto repair :

does it have a spark on the spark plugs?

Customer:

yes

tims auto repair :

ok

tims auto repair :

to me

tims auto repair :

sense it wont fire when your spray starting fluid into the throttle body

tims auto repair :

and it does have a spark

tims auto repair :

i think it has jumped time on the timing chain

tims auto repair :

it does have allot of miles..and i would think the chain has never been replaced

tims auto repair :

fact is

tims auto repair :

if it were in time

tims auto repair :

and has a spark

tims auto repair :

it should fire with the stating fluid

tims auto repair :

regardless

tims auto repair :

your next step is to check te compression of the engine..it should have over 100psi on all cylinders...if not,,it has jumped

Customer:

is it intergrated motor?if it jumps timing chain does it damage valves?

tims auto repair :

yes..it is possible for the valves to hit the pistons

tims auto repair :

sometimes the tensionor will let go,,and cause it to jump time

Customer:

engine compression was 160psi

tims auto repair :

on all cylenders?

tims auto repair :

now?

tims auto repair :

it would start

tims auto repair :

or t least fire

Customer:

only checked 1 cylinder

tims auto repair :

and it has a spark on that cylender?

Customer:

yes

tims auto repair :

strange

tims auto repair :

if that is the case..it is firing at the wrong time...this is unlikley

tims auto repair :

GENERAL DESCRIPTION
The ignition system is a direct ignition system. It consists of the parts as described below and has an electronic ignition control system.
- ECM (or PCM)
It detects the engine condition through the signals from the sensors, determines the most suitable ignition timing and time for electricity to flow to the primary coil and sends a signal to the igniter (in ignition coil assembly).
- Ignition coil assembly (including an igniter and an ignition coil)
The ignition coil assembly has a built-in igniter and ignition coil which turns ON and OFF the primary current of the ignition coil according to the signal from ECM (or PCM). When the ignition coil primary current is turned OFF, a high voltage is induced in the secondary wiring. One ignition coil is in charge of ignition of one cylinder only.
- Spark plug and noise suppressor
- CMP sensor, TP sensor, ECT sensor and MAF sensor.

This ignition system does not have a distributor and high-tension cords but each cylinder has an ignition coil assembly (igniter and ignition coil) and the secondary voltage which occurred in the ignition coil is sent to the spark plug directly. Also, the signal(s) are sent from the CMP sensor to ECM (or PCM) so as to control each ignition coil independently through the igniter (in ignition coil assembly).

tims auto repair :

it is posible for the crank sensor to do this

tims auto repair :

if it isnt the crank sensor

tims auto repair :

i would think it is the pcm-computer

tims auto repair :

i think it is in time if it has this much compression

tims auto repair :

Check crankshaft position sensor referring to Steps 2 and 3 of DTC P0335 Diag. Flow Table in "Computers/Testing/Trouble Code Procedures".

If malfunction is found, replace.

Customer:

does it hav crank sensor whats its location?

tims auto repair :

just posted

tims auto repair :

jeck all fuses before you do anything

tims auto repair :

check

tims auto repair :

again..fact is,,if it is sparking at the right time and has compression,,it should have fired with the starting fluid,,regardless if it has a fuel problem

Customer:

ok

tims auto repair :

i hope i have help you some

tims auto repair :
Customer:

tims auto repair :
Customer:

seems like very expensive fix just bought truck,if pcm was bad would it hav these symtoms described?

tims auto repair :

yes..it is posible

tims auto repair :

but,,check the spark,compression and crank sensor first

Customer:

seems like it would be easier to replace pcm computer first.did some research pcm computer was recalled for defect

tims auto repair :

well..it doesnt codt anything to test

tims auto repair :

the pcm will cost

tims auto repair :

tims auto repair :

hitting every key exept the right one..lol

Customer:

sorry dont understand ur response

tims auto repair :

tims auto repair :

before buying the pcm

tims auto repair :

just to make sure

tims auto repair :
