98 5.7 Tahoe was stolen and recovered. I have not checked the Engine VIN, but I am fairly certain the thief swapped out the worn out 5.7 with 300K with another 5.7. It appears this engine has sat for a while, but it has good oil pressure and compression. I have reconnected the wiring and security light is off. I have spark. Fuel pressure is good at the valve, but no fuel in the cylinders. I poured some gas down the throttle body along with a little Lucas. Still no cough or sputter. Could the spider injectors be clogged bad enough to keep fuel from getting to any cylinders?
