Opel Astra 17DTL 1999 error P1335

[darius89]

Hi, does anybody has problem with this error :
P1335 (A) Injection Pump: no engine speed input signal from control unit.
Car starts hardly , sometime it starts 5-10 times without any problem and no error if I starting without delay.....
after 1 minute if I try to start I got error and starts hardly, but second strt without delay starts ok ...????? any idea ???
All wiring ECU <=> pump, ECU<=> CPS ok tested
Crankshaft sensor from good running car
Pump electronic head from running car
On scan I have good signal from pump and crankshaft
injectors ok

Check rpm and pump speed in live data. I think pump speed is 1/2 engine rpm.
A part of the electrical circuit is inside the engine ecu. That can also be defective.

Dodgy engine control relay. Like the VW one"109" but GM version.

5. More faultcodes ?
6. Controll relay like asmn wrote.
7. Bad solderjoints in ECU

5. no, only P1335
6. relay ok

if you long to turn the starter, the engine starts and runs normally and P1335 error disappears.

8. Both cam and crank sensors new ?
9. How much is the Pump pressure vile cranking ?
