Hello. Recently my 99 camry 2.2 auto shut off on freeway. Found out to be timing belt slipped. Put a new one on, did compresstion test, everything looking good. Went to crank, just turns over. Getting spark, fuel pump working, NO codes, timing is good, compression is excellent, battery fully charged. Swapped cam and crank sensors, swapped ECU's, fuel filter is new, checked fuses. Went and checked injectors and im getting constant voltage on one terminal but other one im getting NO signal.

Car will run if i spray cleaner in the intake unit i stop, than car will stop.
The injector signal is whats wrong. Wires look good, car ran good b4 tbelt slip.

Any ideas on what is causing no signal? Where is the signal supposed to come from??

Read the codes.

There are no codes. Had my scanner hooked up all the time i was diagnosing and nothing.
