Any engine warning warning lights come up on the dash prior or after the fault occurs?

Have you had any checked or investigated already upto now to help solve this?

Hi there no there's no warning lights on .

Expert:  Robert replied 2 years ago.


Ok..Its possible you may have have a faulty coolant temp sensor - this actually located on the thermostat housing - the ecu uses that sensor too to determine exactly what temperature the engine in to calculate how much fuel is if the engines cold then the more fuel/air is needed until of course the engine heats up then thats trimmed off..its possible the sensor is acting up and ecu thinks the cars engines still cold..Also another check as and when that fault occurs is check the enigne still has spark - you need to remove depending on which ignition systems on it either the leads from no1 cylinder or coil and using a spark tester see if the engine still gets spark when its no starting..if not then quite possible the crank sensors failing or going open circuit..normally if hooked upto a diagnostic machine whilst the cars running can live data monitior or record as and when the fault occurs that way they will have better scope as to what sensor is dropping if any..
