How do I check the timing marks?
See Figures 1 through 12
Special tools are needed for this job.

It is important that an aligning tool is used to avoid seal damage and to ensure a tight, even seal fit.

The timing gear cover retaining bolts vary in length and must be installed in the same locations from which they were removed.

Been going over the instructions you sent me for eval the timing in my engine. I dont understand exactly what Im supposed to do once I get the timing cover off and how this is going to take care of my problem. Help me understand to make it easier for me to tackle this problem.
1. changed out solenoid, battery, ignition coil, water pump, radiator,
2. cranks over normally just wont keep running
3. died driving down street
4. fuel filter changed 6 mos. ago
5. gag gauge does not work
6. seems like it was losing power .
7. getting spark to the plugs
8. fuel pressure test is foreign to me. did remove gas line going to carbuerator just past
fuel filter with good flow of gas while cranking
9. in past and was ok. replaced all vacuum hoses about 6 mos. ago. can you perform vacuum test w/o engine running?
10. new battery. alternator checked out ok at autozone
11. tried suggestion to put some gas in carbuerator with no change or even temporary run of engine
12. can the problem be the vacuum system itself, would that prevent the engine from starting even for a sec?
