hi it moves ever so slightly if you put you foot all the way down and then start the engine it goes up to 1500 revs but then goes back down to just under 1000.Noticed the vacume pump was shattered in side so have also changed that but still no change.

Two of the codes point to a throttle valve/wiring/ecm problem,did you remove the cover from the throttle valve,drain any oil out and clean the circuit board ?
P1125 08 Throttle Actuator Feedback Circuit Malfunction
P0638 04 Electronic Throttle Control Circuit open
P0180 07 Fuel Temperature Sensor Circuit High Input
P1322-73 code not applicable to this engine

just managed to delete all the codes using a obd2 scanner.all except 112508.would this cause the no acceleration?
once again thank you for your help and advice.

The code would indicate a problem with the sensor signal,check fuse FE21 in the UEC is ok first
but have you checked the plug to the throttle valve is in ok,no corrosion,no breaks etc
it's the light blue/orange wire from terminal 4 on the connector to the ecm connector XC52,pin 52

hi yes the connector was loose.
however back to the drawing board....
now no codes at all and no throttle response at all.
its now gone from nearly attempting to rev to now nothing at all (just idling at 900) would the timing have any effect to this as all that has been done was the cam belt.

Wonder if you have bent a pin when checking the connector?

run it for a while and you should get a code or two appear,you could really do with opcom and a multimeter though

hi great advice so far many thanks
now after running the engine for a while the sensor for the cam shaft 034029 appeared.i have checked the connection and then removed the engine mount and casing to investigate.
the timing marks are not lining up any more is that normal?
i decided to re do the timing belt with all marks lining up.however the cam shaft wont line up when it gets close to the mark it jumps forward i could have somebody hold it in place to do but am concerned that this didn't happen when first done.
has anyone seen this before?

when turning the engine over twice the marks do not go back.
how is the best way to ensure tdc?
